摘要
采用显微硬度计、电子拉伸试验机、光学显微镜和TEM等，通过与Cu-0．1％Ag合金对比，分析了Cu-0．1％Ag-0．06％Ce合金和Cu-0．1％Ag-0．1％Cr合金的抗软化性能、合金元素的作用及结构形貌特征。结果表明：Cu-0．1％Ag合金中分别加入铬和稀土铈后，综合性能明显提高，软化温度分别提高了110℃和35℃；稀土化合物以小球状分布在晶体内，细化晶粒，提高强度和抗软化性能。
Resistance to softening properties,the effects of alloy elements and microstructures of Cu-0.1%Ag-0.06%Ce and Cu-0.1%Ag-0.1%Cr alloys were analyzed and compared with Cu-0.1%Ag alloy, by using hardometer ,electronic tensile testing machine, optical microscopy and TEM,etc..The results indicate：the comprehendsire properties of Cu-0.1%Ag alloy remarkably enhance after adding traces of Cr and rare-earth Ce elements respectively, softening temperatures rise by 110℃ and 35℃ respectively and the rare-earth compounds of small ball shapes can refine grain sizes and improve strength or hardness and resistance to softening property.
