铍青铜是含有铜、铍和镍元素的三元合金,经热处理后能大幅度提高强度、硬度和弹性极限,常被用于罗盘、钟表及特殊用途的弹簧、轴承等精密防磁零件中。铍青铜的热处理分为固溶处理和时效两个步骤。固溶处理的温度因化学成分的不同大都控制在780～960℃之间。由于铍青铜在高温下极易氧化,冷却时容易脱溶,所以给热处理操作带来了很大的困难。根据国内有关资料介绍,铍青铜固溶处理均采用氨气、氩气炉加热。在
Beryllium bronze is a ternary alloy containing copper, beryllium and nickel. After heat treatment, it can greatly enhance the strength, hardness and elastic limit. It is often used in precision anti-magnetic parts such as compass, watches and special purpose springs and bearings. Beryllium bronze heat treatment is divided into two steps of solution treatment and aging. The temperature of solution treatment due to the different chemical composition are controlled at 780 ~ 960 ℃. Because beryllium oxide easily oxidized at high temperatures, easy to dissolve when cooling, so to the heat treatment operation has brought great difficulties. According to the relevant domestic information, Beryllium Bronze solution treatment are used ammonia, argon furnace heating. in
