摘要(Abstract):

通过真空熔炼的方法制备了Cu-0.80Cr-0.30Zr-0.03P合金,研究了合金经冷变形及固溶时效处理后的导电率和显微硬度等性能,绘制了Cu-0.80Cr-0.30Zr-0.03P合金的相变动力学(S)曲线以及等温转变动力学(TTT)曲线,同时分析了合金的时效析出相种类。结果表明:Cu-0.8Cr-0.30Zr-0.03P合金的最佳热处理工艺为900℃×1 h固溶处理,之后80%冷变形,最后450℃时效4 h,此时合金的导电率、显微硬度、抗拉强度和伸长率分别为84.03%·IACS、187.7 HV0.2、428 MPa和9.8%,对合金时效后的衍射花样进行标定,确定析出相为Cu10Zr_7。
