ABSTRACT:
Disclosed is a method for mechanically compositing metal powders to produce composite metal powder material having a substantially homogeneous dispersion of refractory particles dispersed throughout a metallic matrix and being substantially free of oxide scale. Preferably the composite powder has a mean particle size less than about 50 microns and a mean grain size of less than about 0.5 microns which method comprises milling the metal powders with one or more refractory compounds in the presence of a cryogenic material.
