Yes I have, but they did not have any books on the subject. (I am
looking for tungsten alloy P/M, not cemented tungsten carbides.)
Admittedly, tungsten P/M is not a large field, so there may not be many
books on the subject .....
Sorry Alvin, I think I mis-spoke ...
Tungsten/tungsten alloy processing is P/M by necessity, due to the fact
that the extremely high melting temperature of tungsten makes it so
difficult to form by casting.
I think cemented tungsten carbide is also made by P/M pressing and
sintering techniques, too, by pressing a composite mixture of tungsten
carbide particles and cobalt powder, then sintering the green compact
under pressure to densify the compact to full density. (hence the name
cemented tungsten carbide--- tungsten carbide particles "cemented" into
a matrix of cobalt metal)
I am looking for tungsten/tungsten alloy P/M, not cemented tungsten
carbides. I have a background in "conventional" ferrous P/M, but I am
about to take a new job dealing with tungsten and tungsten alloy P/M,
and I want to try to get up to speed quickly since I have next to zilch
knowledge of that area of P/M.
I think the Metal Powder Industries Federation may have published
articles on tungsten alloy processing in the past ... I will try to get
some reprints of those if I can, but I was wondering if anyone more
knowledgeable on the subject than me would have some suggestions on
their favorite reference books based on their own experience. I have
been told there is little published on tungsten P/M.
Sorry for the confusion.
