method for powder metallurgy manufacture of alloys on titanbasis with small korngroesse.

摘要

A process for forming a titanium base alloy comprises compacting a powder formed of particles of titanium or of a mother alloy thereof and of a dispersion of fine particles of a product curbing the growth of the grain size, in a proportion per volume which is less than that which would lead to the formation of a continuous layer of fine particles about the particles of titanium powder. Then the alloy is heat treated at a temperature higher than the point of transformation into phase beta and quenched. The product is typically selected among S, P, B, As, Se, Te, Y and the lanthanides.
