摘要: 用化学还原法制备了Fe－Cu过饱和团溶合金粉．Fe－Cu纳米粉中含有少量硼可扩展fcc相的成分范围．合金树体中Fe和Cu的原子比达到4：1时，主相仍保持fcc结构，Lcc相区的范围可超过采用机械合金化法制备的Fe－Cu合金．对样品的退火处理研究证明Fe－Cu系过饱和固溶合金的fcc相相当稳定．认为Fe－Cu合金的这种行为是由于合金中含有少量硼引起的

关键词 ：化学还原法, Fe－Cu合金, 过饱和固溶体

Abstract：The nanometre-sized Fe-Cu supersaturated solid solutions were prepared by chemical reduction. There is a small amount of boron dissolved in the alloys. The solid solu-bility of fcc-phase is largely extended to about an atomic ratio of 4: 1 for Fe and Cu. The range of fcc phase in the Fe-Cu alloy goes beyond the scope of that prepared by mechanical alloying. The fcc phase was found to be rather stable during heat treatment. The large solubil-ity extending and high stability of fcc phase are caused by the small amount of boron con-tained in the alloys.

Key words： chemical reduction Fe-Cu alloysupersaturated solid solution
