| 摘 要： | 用化学还原法制备了Ｆｅ－Ｃｕ过饱和固溶合金粉。Ｆｅ－Ｃｕ纳米粉中含有少量硼可扩展ｆｃｃ相的成分范围。合金粉体中Ｆｅ和Ｃｕ的原子比达到４：１时，主相仍保持ｆｃｃ结构，ｆｃｃ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了Ｆｅ－Ｃｕ系过饱和固溶合金的ｆｃｃ相相当稳定。

| 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. |
