铜—铬—锆—镁合金属于加工硬化和沉淀硬化复合强化的新型电极材料,它既具有高的强度和高的软化温度,又具有优良的导电性。本文应用光学及电子金相、电子探针扫描等微观分析手段以及机械性能试验、电阻测量等方法,研究了冷变形及时效对固溶淬火后的Cu-0.27％Cr-0.11％Zr-0.03％Mg合金线材组织和性能的影响,并时该合金的性能进行了评价。
Copper-chromium-zirconium-magnesium alloy belongs to a new type of electrode material reinforced by work hardening and precipitation hardening. It has both high strength and high softening temperature as well as excellent electrical conductivity. In this paper, the effects of cold deformation and aging on the properties of Cu-0.27% Cr-0.11% Zr-0.03% after solution-quenching were studied by means of microscopic analysis such as optical and electronic metallography, electron probe scanning, mechanical property test and electrical resistance measurement. Mg alloy wire structure and properties of the alloy, and when the performance of the alloy were evaluated.
