    • 摘要: 对经不同热处理后铜银锆合金的性能进行了研究, 通过透射电镜分析了合金中析出相的种类及形貌。结果表明: 合金经920 ℃×40 min固溶水淬+30%冷变形+420 ℃×3 h时效空冷处理后, 能获得较好的力学性能与电学性能, 硬度为123 HB, 电导率为88.8%IACS, 室温抗拉强度为430 MPa, 断后伸长率为13.5%, 断面收缩率为45.2%; 热处理后合金基体上弥散分布着Cu5Zr析出相和粗大的铜银锆饱和固溶体。

       

      Abstract: The properties of CuAgZr alloy after different heat treatments were studied, and the type and morphology of precipitation phase were analyzed by transmission electron microscopy. The results show that the alloy could obtain fairly good mechanical and electrical properties after it was treated by such technologies as 920 ℃×40 min solid solution (water quenching), 30% cold deformation, and 420 ℃×3 h aging(air-cooling), and its hardness, conductivity, room temperature tensile strength, elongation and reduction of area were 123 HB, 88.8%IACS, 430 MPa, 13.5%, 45.2%, respectively.Cu5Zr precipitation phase and coarse solid solution of CuAgZr distributed in heat-treated CuAgZr alloy matrix.
