Global Materials Resources-China's Journal of Materials Science and Technology and Acta Metallurgica Sinica plus comments on Superalloy Melting

I am pleased to bring to the (further?) attention of the Materials Science and Engineering community, these two titles from China's Materials Science and Technology community,
1. The Journal of Materials Science and Technology
2. Acta Metallurgica Sinica.

Don't be put-off with either the slow download time not one or two broken links...

Cheers for their effort,

NB. I trust I may eventually receive a response from the author to my original enquiry which brought me to their site in the first place:

"Desulphurization during VIM Refining Ni-base Superalloy using CaO Crucible" in China's JMST.

"I am surprised that my earlier work is not referenced in such work: J. ALEXANDER: "Optimizing deoxidation and desulphurization during vacuum induction melting of alloy 718", & MATER. SCI. TECHNOL. 1985, 1(2), 167-70. Some online references may be found via my pages: http://materialsscienceengineeringdefined.blogspot.com/ Either search VIM or direct link: J. ALEXANDER: "Optimizing deoxidation and desulphurization during vacuum induction melting of alloy 718", & MATER. SCI. TECHNOL. 1985, 1(2), 167-70

Nice to know that others have become interested in such themes [after all this time]. "

PS. There is still (understandably) much discretion by manufacturers on how to achieve "Clean, very low oxygen, dissolved(gas) and total oxygen, (the latter includes oxide particles) together with very low sulphur (mostly oxysulfides) not to mention the very low harmful trace elements obtained in today's large size VIM melting facilities despite low surface to volume ratio limiting mass transfer and chemical exchange withe the vacuum atmosphere.

Yet all the above melt specification, so important for superalloy manufacturing, can be achieved.

cf. Past Boiling Point, Materials World 1 June 2009 by Gaylord Smith, Brian Baker, Lewis Shoemaker of Special Metals Corporation, R & D, Huntingdon, West Virginia, USA who describe the developments of INCONEL alloy 740, suitable for use in the high temperature environments of supercritical boilers for energy generation.

Full article currently available only to IOM3 members, open to all with 2 month delay, I believe.
