Abstract (en)

[origin: EP0290820A2] To produce dispersion-hardened metal alloys with incorporation of not easily reducible particles into a metallic matrix in a second phase, the metallic constituents are initially present as a salt solution, and metal salts or mixtures of such salts are used as starting materials.
