Cu-Ni-Be-X高导电耐磨合金时效特性研究

Study on Aging Chaaacteristic of Cu-Ni-Be-X Alloy with High Electric Conductivity and Wear Resistance

研究了经铸造、热锻、固溶淬火和冷变形后的CU－Ni－Be－X合金在不同时效规范时效后的硬度和电导率变化规律。透射电镜观察及电子衍射分析结果表明，合金中两种析出相及其形貌是影响合金不同规范时效后性能变化的重要原因。

The hardness and electric conductivity of Cu-Ni-Be-X alloy after casting, forging,solution-treat-ment, quenching, eold working, vaied with different aging regimes were studied. The results shown that two types of precipitates and their morphology are important to the variation of alloy properties at differeerent aging regimes.
