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.
