ABSTRACT:
A method of producing dispersion hardened metal alloys which incorporate highly reactive metals or their alloys whose oxides are not adapted to be easily reduced. According to the method, the highly reactive metals of their alloys are added as powder particles to a solution of a salt of a reducible metal which is to form a metallic matrix in which the reactive metals or their alloys are to be integrated, after which the solution is atomized to form particles from which the solvent is removed to yield the final product of the metal matrix with the highly reactive metals or their alloys integrated therein as a second phase.
