Abstract
Abstract Directed to the powder metallurgy production of consolidated metal products wherein the starting material comprises dense wrought particles containing at least 15 percent by volume of a compressively deformable metal with the remainder being one or more other metals or non-metals with the internal structure of the particles being non-porous and with the constituents thereof being intimately united and interdispersed, i.e., mechanically alloyed, said particles, upon consolidation, yielding metal or cermet products having unusual properties and capable of compositioinal characteristics not available as a result of other processing techniques.
