Abstract

An amorphous mechanically alloyed Co67B33 powder has been compacted by hot forging at 200, 300, 400, 500, 700°C applying a load up to 2 GPa in 2 seconds. The density approaches the theoretical value operating under inert gas at 700°C. The alloy structure changes from amorphous to crystalline. Hardness and wear resistance of the material forged at 700°C are superior to those of the starting amorphous alloy as well as to those of an alloy of identical composition obtained by conventional slow cooling of the melt.
