【摘要】 通过对Cu-0.43Cr-0.58Zr-0.031Y合金和Cu-0.20Cr-0.66Zr-0.060Y合金进行不同温度固溶处理后合金硬度和导电率的测定与分析,可以确定Cu-0.43Cr-0.67Zr-0.031Y合金的固溶温度为960℃,Cu-0.20Cr-0.63Zr-0.060Y合金为920℃。运用金相和扫描电镜对固溶后合金的显微组织进行观察和分析,发现Cr是影响固溶温度的主要因素,合金的固溶温度随Cr含量的增加而升高。更多还原

【Abstract】 The microhardness and electric conductivity of two kinds of alloys, Cu-0.43Cr-0.56Zr-0.031Y and Cu-0.20Cr-0.66Zr-0.060Y which be soluted by different temperature, are measured and analyzed. The results show that the soluted temperature of Cu-0.43Cr-0.56Zr-0.031Y is 960℃ and that of Cu-0.20Cr-0.66Zr-0.060Y is 920℃. The content of Cr is the vital factor for soluted temperature, and the temperature is rising with the content of Cr increasing.更多还原
