Abstract
The compacts produced from Ni–Mg metal powders by explosion and intended for commercial alloying of wear- and heat-resistant steels, cast irons, and special-purpose alloys are investigated. The optimum parameters of shock-wave compaction of Ni–Mg–Mo–W and Ni–Mg powder mixtures are calculated and experimentally confirmed. A cylindrical storage ampule with a polymetallic powder mixture is loaded with an explosive charge, which generates a cylindrically convergent shock wave to provide an all-round uniform compression of the ampule. High-density compacts (>98% of the theoretical density) with the same initial phase composition are synthesized from powders with highly different properties.
