摘　　要：通过铜型快速凝固得到了细晶Cu-Sn和Cu-Sn-Fe合金,重点研究了Sn和Fe复合合金化对Cu-Sn-Fe合金的铸态和轧制态抗拉强度的影响。结果表明,复合合金化和轧制变形可使合金的抗拉强度得到大幅度的提高。探讨了合金化和轧制变形对Cu-Sn(Fe)合金抗拉强度变化的作用机理。The fine grained Cu-Sn and Cu-Sn-Fe alloys were prepared in a copper mould with a high cooling rate, and effects of Sn and Fe compound alloying on the tensile strength of casting and rolling Cu-Sn- Fe were investigated. The results show that the tensile strength of Cu-Sn-Fe can be increased markedly by compound alloying and rolling. The mechanism of compound alloying and rolling was described.
