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.

Ni-Mg中间合金的爆炸压实

摘要

研究了由Ni-Mg金属粉末爆炸产生的压块，该压块用于耐磨和耐热钢，铸铁和特殊用途合金的商业合金化。计算并实验确定了Ni-Mg-Mo-W和Ni-Mg粉末混合物的冲击波压实的最佳参数。装有多金属粉末混合物的圆柱形储存安瓿装有炸药，爆炸药会产生圆柱形会聚冲击波，从而对安瓿进行全方位的均匀压缩。具有相同初始相组成的高密度压坯（理论密度的> 98％）是由性质差异很大的粉末合成的。
