采用剧烈旋锻和两步峰时效工艺，获得了抗拉强度为612 MPa、均匀延伸率为5%、电导率为84.7% IACS的高性能Cu-Cr-Zr合金。合金具有良好的超细晶组织和均匀分布的纳米析出相，这是合金优异性能的主要原因。采用旋转旋锻结合两步时效处理的方法制备高性能Cu-Cr-Zr合金，不仅能满足工业对强度和导电性的要求，而且适合大批量生产。
A high performance Cu-Cr-Zr alloy with an ultimate tensile strength of 612 MPa, a uniform elongation of 5% and an electrical conductivity of 84.7% IACS was achieved by the severe rotary swaging and two-step peak-aging treatment. A perfect ultrafine grained microstructure with uniformly distributed nano-precipitates was identified to be responsible for the excellent properties of the studied alloy. The proposed method of rotary swaging in combination with the two-step aging treatment shows good potential for producing the high performance Cu-Cr-Zr alloy, which can not only fulfill the industrial requirement of strength and electrical conductivity, but also is suitable for mass production.
