摘　　要：研究了题示冶金产物（铂族金属富集物）中的快冷物相。主体物相是以Ｆｅ或（Ｆｅ，Ｎｉ）为基体含铂族金属（ＰＧＭ）的合金固溶体相。含Ｐｔ量高的富集物中有（Ｐｔ，Ｐｄ）固溶体相，含Ｓｉ量高的富集物中有赋存ＰＧＭ的Ｆｅ或Ｎｉ的硅化物相；微量Ｓｎ除分布在众多的相中外，与ＰＧＭ生成锡化物相。发现急冷合金化可生成εＦｅ亚稳相、ＦｅＣ亚稳相。各物相中除主体成分外，都含有众多的组元。快冷ＰＧＭ富集物是多种非平衡物相的集合体。The phases in the platinumgroup metals (PGMs)concentrating matter from plasma metallurgy have been analysed. The main composite phases are (γFe, Ni), (Fe, Pt), (Pt, Pd) solid solutions, FeC phase, εFe metastable phase. The subordinate phases are compounds:Ni3Si2, Ni3Fe, PdSn, ζβ phase. With composition change in concentrating matter there occur some differences in phase species and number. The concentrating matter is an aggregate of nonequilibrium phases,which contain platinumgroup metals.
