Physicists defy conventional wisdom to identify ferroelectric material | EurekAlert! Science News
"If you make a strontium titanate film very thin, all of a sudden it becomes ferroelectric at room temperature," "If you make it thicker, ferroelectricity disappears. That's very strange, as it goes completely counter to all the common knowledge regarding the thickness effect on ferroelectric properties." says Alexei Gruverman, a University of Nebraska-Lincoln physics and astronomy professor who worked on the research.

Materials Selection for Resistance to Abrasion_eg. for applications such as Iron Ore Slurry Transportation
An impressive and succinct presentation of materials,mainly special steels for use in ore mineral transportation as slurry often over huge distances.
This most usefull graphical representation of types of materials that can be transported via pipeline, slurries, is given below. On the upper left (LHS) of the diagonal, the materials to be transported are plotted according their Mohr's hardness on a log10 scale (y-axis) against pipeline candidate materials mainly steels, with some ceramic (coatings) classified according to their hardness, both Brinell and Rockwell tests, on the lower right (X-axis) The inclusion of soft materials such as general plastics, talc and the more and more in view graphite, (nanoapplics) provide a strong contrast which highlights the resistance of the steel tube contenders.
A table of contents from his short and to the point publications reads as follows:
-Typical Mine Applications.
-Types of Wear.
-Hardness.
-Piping Materials.
-Material Alloying: metallurgy for strength and harndess.
-Heat treatment (quenching technology) to harden inner surface,
while maintaining a more ductile exterior surface.
-Wear Tiles and Inserts: tiles are of course made from materials that are harder and more abrasion resistant than the base steel piping.
-Rubber/Poly Lined Pipe.
-Double Wall Pipes.
-BiMetallic Pipes. (advantages, but without the disadvantages of the double wall pipes).
-System Design Considerations:
Particle size, shape, and hardness, Particle Velocity,

Taking the heat off the chip_Global Thermal Interface Materials Report 2015 - Status, Opportunities, Market Forecasts to 2025 -- DUBLIN, June 5, 2015 /PRNewswire/ --
Here is a short rapid introduction and overview to a still hot topic-materials to markets
The contact area between high power, heat generating components and heat sinks can be as low as 3%, due to the micro-scale surface roughness. Thermal interface materials are required to enhance the contact between the surfaces, and decrease thermal interfacial resistance, and increase heat conduction across the interface.
Proper selection of Thermal Interface Materials (TIM) is crucial for the device efficiency. Instead of sophisticated cooling technique, it is often better to invest in the interface material. Without good thermal contact, the use of expensive thermally conducting materials for the components is a waste.

EUROSUPERALLOYS 2014_ MATEC Web of Conferences. Open Access
"EUROSUPERALLOYS 2014 – 2nd European Symposium on Superalloys and their Applications"
was held in Giens, France in May 2014.
Ten full sessions and eleven poster sessions were held on many (most) aspects of Superalloys processing and properties. Superalloys, as the name implies, have superior properties. They are used in applications involving high demands in performance and reliability namely strength high temperatures and corrosive environments such as those encountered especially in aircraft_aero-engines and improved energy production plant.
List of themes is as follows: please excuse the EU for allowing US spelling rather than the original and UK spelling behaviour
I did notice however that neither in these open access conference papers nor in web based available manufacturers specifications that the limits on such common trace elements as S (sulphur) and P (phosphorus) appeared high when compared with the practice and practise, of which I am aware. Admittedly dated! However I honestly report here that a couple of my ex-colleagues involved in such advance metallurgical processing and development in PM (powder metallurgy) requested "current S levels be lowered from a commonly specified 0.015%Smax. I was able to respond immediately and informed my client-collegues that the first trials had already proved successful as usual with "my" desulphurization technique.
My peer reviewed paper is now freely available to our members of IOM3_The Institute of Materials Minerals and Mining entitled:
"Optimizing deoxidation and desulphurization during vacuum induction melting of (Super) alloy 718. J.Alexander, Materials Science and Technology,(MST) published Feb. 1985.(MST's 2nd issue).
Now let's not be shy. My Indian colleagues (most of whom are retired today) from the MIDHANI, Ministry of Defence plant in Hyderabad can honestly vouch for my desulphorization performance. As guarent for the "three melt-shop know-how transfer contract, I was called upon to assist during start-up in Hyderabad. Unfortuneately the only raw material for the very low P (phosphorus) grade to be made had about 3times mor P than our recommended raw material. Well, under some pressure from the then, chairman no less, I accepted the challenge and brought the damed thing into the aimed spec.
I was never informed whether the final product achieved the result originally set in the "Know-how" agreement.
Post Scriptum:
Thing must have sorted themselves out considering that very recently India has also bought the french jet fighter The Rafale and for good or bad Mr. Mittal has bought over the company where I had enormous fun both at work and for pleasure. I took up my soccer game after a too long lay-off during studies and early laboratory research work..
I do hope you enjoy sharing my experience.
Best regards.

Imphy Special Steels & Alloys Steelworks_Off the EU radar! & My Local weather here in the centre of France_Info Update
I have just included Meteo France's weather provision for my area. The meteo station is nearby (a couple of kms away) so is pretty reliable. Potential visitors will find the city of Nevers lies on the the famous N7 road and on the banks of the Loire river. Access to water from France's longest river La Loire led Colbert to choose the region for the "once"! famous steelworks at Imphy situated 15kms from Nevers. The much modernised factory where I had the privilege to work for many years researches and manufactures a huge variety of special steels, and alloys. They range from steels for aircraft undercarriage through delicate to manufacture iron-chromium(Fe-Cr) and iron-chromium-nickel (Fe-Cr-Ni) stainless, corrosion resistant steels. They are the world reference for weldable iron-nickel (Fe-36%Ni) Invar sheet metal for liquid gas sea transportation. The range of Fe-Ni alloys, with or without cobalt (Co) runs from Fe-30%Ni to Fe-80%Ni with dilatometric, magnetic and electrical properties. If this is not a sufficiently, highly sportive, endeavour then add the the aero-engine alloy family: The famous Superalloys; Inconels,Udimets, Waspalloys and an early competitor in power metallurgical research, development and manufacture; I personally had privileged fun with Superalloy development; melting and refining, introducing revert material into aeroengine alloys to meet the most stringent requirement of the civil aviation authorities and the major aeroengine manufacturers, GE-SNECMA,(USA-FR) Rolls Royce,(UK) Pratt & Whitney (USA), Turbomeca (Fr), MTU(Ger). Refs below
I know that at least one of my ex-colleagues must be pleased that France's Rafale Fighter Jet aircraft is now selling, namely Dr. G. Raisson who got the powder metallurgical manufacturing up and running. Unfortuneatly two others who deserve great credit are nolonger with us: My long time boss Y. Honnorat, (Ecole Centrale Paris) one of the most brillant minds I have ever encountered and my dear friend and ex-colleage Dr. James H. Davidson (ex Sheffield Univ.& Imphy Research Centre).

(Cheers and Kind regards)
My presentation of the local weather here, has lead me to decline with many thanks this once proud special steels and alloys plant. Proud to have developed the ideas of Charles Edouard Guillaume, whom my British metallurgical colleagues, members of IOM3_Institute of Mining, Minerals & Materials consider (tongue in cheek) to be the only winner of the Nobel Prize in Metallurgy (Physics of course) Guillaume was based at the International Bureau of Weights & Measures (NPL-UK equivalent)and his "associate" in Industry (Imphy based) Pierre Chevenard. I have had the privilege of working with Research and Manufacturing Development Metallurgists who have personally known Pierre Chevenard.
Now I am reporting this due to my astonishment upon reading the EU-report: Metallurgy Europe –A Renaissance Programme for 2012-2022 list in Annex 2. Potential Beneficiaries from European Industry
(non-exhaustive!)
Non-exhaustive, is no excuse! This unique entity once"Imphy SA" Three melt-shops, Electric Arc mini mill at least 20years ahead of USA, It's own on site R&D centre, developing its own materials while others in France bought US technology and know-how. Plus three first class laboratories, 1 Chemical Analysis for production and quality requirements-cf. scope of materials above. 2. Mechanical properties, from cryogenic to high temperature corrosion and strength. Macroscopic and microscopic control and development. 3. Physical properties lab for dilatometric,magnetic and electrical control and development.
That this once proud industrial innovator comes under the relatively unknown name APERAM-Chairman Mr Lakshmi Mittal. What it is today, I can hardly imagine. Last news I had was that the 1500 person strongly integrated Imphy site (Imphy SA) in my days appears to be a hotchpotch composed of : Steel melting-Mittal, Special Iron Steels, Stainless Steels & Superalloys "Techphy-Eramet_Aubert & Duval". Will this new attempt to bring perhaps a sense of unity and the strong sense of identity of my days succeed? Will the latest rationalisation demotivate under the still unknown company, called APERAM, unknown at least in the above referenced EU listing.
PS.
I do hope that success is on the agenda for the sake of current employees and for our relatively deprived region, easily forgotten also by our regional capital of Bourgogne (Burgundy) the city of Dijon. No help in view alleviated by transportation difficulties. Indeed it is much easier to travel to Paris or Clermont-Ferrand and should I dare say more useful? National plans for an enlarged Burgundy will penalise further our "West Burgundy" On the EU french divide we are as far from capitol Strasbourg as is possible (Grand Est-Greater East). Perhaps Paris in it's plans for the greater Paris_Isle-de-France will include our city Nevers and our department (county) La Nièvre and so benefit from the economic attaction, and over-populated capital, Paris.

METAL 2010 -Impressive List of free papers on: Steels & Steelmaking, Surface Eng. Non-Ferrous Metals & Alloys in English, from the Cech Republic's Symposium Metal 2010
This post, one of several to be done (TBD), was originally motivated by my search into manufacturing work on low density automotive sheet steel recently published in Nature. If readers wish to carry out their own reseach in this, or better, contribute to my approach, you will find the Nature publication, reference entitled "Brittle intermetallic compound makes ultrastrong low-density steel with large ductility" together with the abstract at the end of my post.
Now in the course of my search I unearthed quite an impressive librairy of freely available papers on Steelmaking,steel properties and metallurgy.

Brittle intermetallic compound makes ultrastrong low-density steel with large ductility
Nature 2015, 10.1038/nature14144
Abstract:
Although steel has been the workhorse of the automotive industry since the 1920s, the share by weight of steel and iron in an average light vehicle is now gradually decreasing, from 68.1 per cent in 1995 to 60.1 per cent in 2011 (refs 1, 2). This has been driven by the low strength-to-weight ratio (specific strength) of iron and steel, and the desire to improve such mechanical properties with other materials. Recently, high-aluminium low-density steels have been actively studied as a means of increasing the specific strength of an alloy by reducing its density. But with increasing aluminium content a problem is encountered: brittle intermetallic compounds can form in the resulting alloys, leading to poor ductility. Here we show that an FeAl-type brittle but hard intermetallic compound (B2) can be effectively used as a strengthening second phase in high-aluminium low-density steel, while alleviating its harmful effect on ductility by controlling its morphology and dispersion. The specific tensile strength and ductility of the developed steel improve on those of the lightest and strongest metallic materials known, titanium alloys. We found that alloying of nickel catalyses the precipitation of nanometre-sized B2 particles in the face-centred cubic matrix of high-aluminium low-density steel during heat treatment of cold-rolled sheet steel. Our results demonstrate how intermetallic compounds can be harnessed in the alloy design of lightweight steels for structural applications and others., Hansoo K. et al

Where to Look for Insight-Innovation = Insight _ don't keep a good thing to yourself.
Where to Look for Insight:
Image ref. MATT CHASE
Hear the word “innovation,” and you might think of an R&D lab, a design group, or a start-up venture. But today innovators are in demand everywhere—from the factory floor to the salesroom, the IT help desk to the HR department, the employee cafeteria to the C-suite.
Innovation isn’t a department.
It’s a mindset that should permeate your entire enterprise.
No matter the venue, the feedstock for innovation is insight—an imaginative understanding of an internal or external opportunity that can be tapped to improve efficiency, generate revenue, or boost engagement. Insights can be about stakeholder needs, market dynamics, or even how your company works.
Several Fortune 500 companies have been founded on a single insight about what customers want. Starbucks brought a little bit of Italy to coffee shops. Home Depot gave do-it-yourselfers access to professional supplies. The Body Shop was built on the notion that buyers of beauty products care about humane animal-testing practices. Inside your company, insights can lead to more-efficient operations, simplified processes, or leaner structures.
Insights can be powerful, but how do you find them? Should you brainstorm with colleagues? Sift through masses of data? Simply introspect? Or carry on as usual and wait for the proverbial apple to fall on your head?
In our combined half-century of working with innovators at start-ups and within large corporations, we’ve found that the best insights tend to come from sources that can be categorized. We recognize that many people arrive at great ideas more or less serendipitously, but we nevertheless believe that it’s possible for individuals to approach innovation in a more systematic way.
On the basis of our experiences with and research into entrepreneurial ventures and product-development groups in varied industries around the world, we have outlined seven “insight channels” that can be used by would-be innovators in any function or role. They are listed below. By periodically tuning in to these channels and methodically running through them, you can focus your imagination, organize thinking, spur creativity, and find valuable ideas for growth.
Seven Insight Channels
Anomalies
Examine deviations from the norm
Do you see unexpectedly high or low revenue or share in a market or segment? Surprise performance from a business process or a company unit?

Frustrations
Pinpoint deficiencies in the system
Where are customer pain points for your products, services, or solutions? Which organizational processes or practices annoy you and your colleagues?

Anomalies.
Businesses today are awash in data. Innovators pore over this information looking for promising ideas, but often they focus on means and averages, which lead to broad conclusions. Sometimes the real opportunities lie in the results that deviate from business as usual.
Consider an anomaly in global e-commerce. One might think that Russia, with more than 100 million middle-class consumers and 75 million internet subscribers, would be an attractive market for online retail. However, e-commerce accounts for a paltry 1.5% of total retail sales in the country. The entrepreneur Niels Tonsen recognized why: The Russian postal system is very unreliable, and few consumers have credit cards. This insight led Tonsen to create an online clothing store, Lamoda, which employs an army of couriers to deliver customers’ purchases to their homes, pick up cash on delivery, and even offer fashion advice. By providing an innovative experience that effectively brings the store, the style consultant, and the cash register to the customer’s front door, Lamoda built a very successful e-commerce business, uniquely suited to the Russian market. (See also “The CEO of Ozon on Building an e-Commerce Giant in a Cash-Only Economy,” HBR, July–August 2014.)
The smart innovator knows to notice and then follow up on surprising data. To look for anomalies, ask questions such as: Is your market share or revenue abnormally low or high in a geographical market? Are
you having unusual success with a specific customer segment? Are some of your salespeople unusually productive? Are some of your suppliers able to deliver unusually quickly? Then dig deeper. The deviant numbers may be the tip of the iceberg, hiding a valuable insight below.
Confluence.
When several trends come together, their intersection can be fertile ground for insights. For instance, the confluence of mobile telephony growth, social networking, and increasingly short attention spans has spurred the creation of social media applications including Vine, which allows the sharing of short videos; Tinder, a GPS-linked matchmaker; and Snapchat, which deletes anything sent through it from the receiver’s phone in a matter of seconds. Evan Spiegel and his Snapchat cofounders built on two more-specific social media trends: the urge to broadcast life as it happens and growing concerns over privacy. People express themselves spontaneously on Snapchat without worrying about self-censorship.
New social habits, technologies, and areas of interest are forming all the time across all facets of life. The smart innovator looks at how they fit together. Ask yourself: What are the major economic, demographic, and technological trends affecting my organization, industry, or market? How do those trends intersect? For instance, if you combine an aging population (a demographic trend) with mobile connectivity (a technology trend) and rising health care costs (an economic trend), you can mine the intersection to create services such as remote health care monitoring for seniors. Similarly, if you combine the rising costs and difficulty of sourcing talent with the widespread availability of mobile video, you can see an opportunity to create a video-based recruitment application to screen a large number of candidates at a low cost.
Frustrations.
Life’s irritations are often a terrific source of ideas. In the late 1990s Mark Vadon, a young consultant, went shopping for an engagement ring and found the experience intimidating and difficult. The system for categorizing and valuing diamonds is complicated, and eager salespeople only add to the pressure. Vadon reasoned that many other men were equally put off—an insight that led him in 1999 to found Blue Nile, an online jewelry dealer that offers useful tutorials and information on gems. Today the company is the largest online retailer of diamonds and sells some $250 million worth of engagement rings a year—more than 4% of total sales in the U.S. market.
Many people arrive at great ideas more or less serendipitously—but it’s possible for individuals to approach innovation in a more systematic way.
Vadon’s experience shows the value of paying attention to what annoys people and then fixing the problem. Put yourself in the shoes of customers, colleagues, or suppliers and ask: What’s most frustrating about your products, processes, or workplace? What bothers you personally about your business? What work-arounds do people use to get their jobs done? How could they be improved upon? Can you make customers’ lives easier or company meetings less painful? Can you reduce the hassles your suppliers face? If you feel people’s frustrations, you can find valuable innovation opportunities.
Orthodoxies.
When something has always been done the same way on your team or in your organization or industry, it’s worth asking if there’s an alternative. Traditions often block potential innovations because people are reluctant to abandon the tried-and-true. But when conditions change, so must traditions.
In the defense industry, for example, manufacturers have long focused on building expensive and sophisticated missiles, such as Raytheon’s Tomahawk, that sell for more than a million dollars; even the cheapest offerings, such as Lockheed’s Hellfire, cost upward of $100,000. These missiles are developed with customer funding (from the U.S. Department of Defense) and are custom-designed to be smart and powerful so that they can take out tanks and other large targets. But at Raytheon (a company to which Mohanbir Sawhney has provided consulting), the 25-year veteran Steve Ignat and his team recently upended that status quo.
Knowing that the United States and its allies needed cheaper, stealthier missiles to effectively target small groups of terrorists on the ground, they created a low-cost manufacturing facility (dubbed the Bike Shop) and, without even courting a single customer, used parts from existing production programs to assemble exactly those sorts of weapons. One of the missiles they built, the Griffin, is now in high demand.
Orthodoxies hide in every organization, industry, and market. To uncover them, ask yourself: What beliefs do we all hold sacred? Why do things have to be this way? What if the reverse were true? What opportunities would be opened up if we abandoned those assumptions and beliefs?
Extremities.
Businesses, appropriately, spend most of their time concerned with their mainstream stakeholders. But sometimes it is the “positive deviants,” as Oxford University’s Richard Pascale calls them, who are a rich source of ideas or insights, teaching us innovative ways to overcome incredible odds or solve seemingly intractable problems.
In May 2014 the famous Harvard law professor and activist Larry Lessig created Mayday, a political action committee to address the issue of corporate money in politics. The PAC would use community- and internet-based “crowdfunding” to raise similar amounts of money directly from citizens. As of August 25, 2014, it had raised $7.92 million from more than 55,000 contributors.
Positive deviants may be visionary customers who can help you see trends before they become mainstream. They may be manic coworkers who are passionate and don’t take no for an answer. They may be enlightened shareholders who can help shape your company’s strategy. Innovators must look at the fringes of stakeholder groups and ask: What can we learn from those who are most intense in their complaints or enthusiasm that we could apply to our company or our role?
Voyages.
When business turns stale, innovators get out of their own offices to visit “customers”—whether that means employees they manage, colleagues who rely on their work product, or the people who buy their goods and services. These “voyages” into different worlds are necessary because all behavior takes place within a rich sociocultural context; it’s impossible to understand what others are thinking when you’re sitting alone at your desk. Designers and product developers have long understood how important it is to take this anthropological approach.
A few years ago, Jennifer Hargreaves, a manager at the financial software company Intuit, was tasked with creating a new version of the company’s popular QuickBooks product for nonprofit organizations. Her first step was to volunteer at a local charity. After immersing herself in the new context—helping to manage the organization’s accounts for a few months—she noticed sharp differences between for-profit and nonprofit financial management processes. The focus was fundraising, not sales, and donors, not customers. This on-the-ground research helped her brainstorm extra features—such as the ability to track donations, pledges, and grants separately and to allocate expenses to particular initiatives or programs—for the new QuickBooks Premier Nonprofit, which she later launched to positive reviews and sales.
Anyone can make similar voyages. Learn how your stakeholders live, work, and behave. Ask yourself: What are the social, cultural, and environmental factors that affect their preferences and behaviors? How can we create solutions that respond to those factors?
Analogies.
Sometimes other teams, business units, companies, or industries have adopted useful ideas or systems that haven’t crossed the border, so to speak. Can you import innovation—even from a place that seems far removed or exotic?
Greg Lambrecht came up with his Coravin Wine Access System by co-opting ideas from the world of surgery. An MIT-trained engineer and an oenophile, he grew tired of uncorking bottles that he didn’t want to finish in one night, only to have the fine wine start to oxidize and deteriorate. Wouldn’t it be wonderful to be able to drink just one glass while leaving the rest perfectly preserved? He knew that surgeons had started using extra-fine needles to ensure minimally invasive surgery and wondered if the same type of needles could be used to draw wine from a bottle. He tested and developed the idea over more than a decade, and despite a few setbacks, Coravin has been well reviewed and is now widely available.
We advise innovators to study a wide range of unrelated functional groups and industries to look for analogies that they can adapt to their domains. After all, innovation is not about bringing something new into the world. It’s about usefully applying something that is new to the situation, no matter the purpose for which it was invented.Our list of insight channels has evolved over the years and will no doubt continue to change and grow. Other observers could probably add a few categories of their own. But we’ve consistently found in our research and work that these seven are powerful drivers of innovation. Although they’re most commonly used by entrepreneurs, developers, and designers, they can help you in any role and any context where new thinking is required. Few people find great ideas on a blank canvas. Most of us need our imaginations channeled.
