摘要
铍青铜具有良好的力学性能,弹性,导电、导热性能,以及无磁性,耐寒、耐磨、耐蚀等。铍青铜的性能主要取决于热处理包括固溶和时效处理。铍青铜零件固溶处理应在木炭、氨分解气或酒精裂解气等保护介质中进行。时效也是铍青铜的一道重要热处理工序,包括欠时效,正常时效,过时效及改进的分步时效、双重时效等。介绍了常用铍青铜的化学成分及其经不同工艺热处理后的组织和性能。
The beryllium bronze possesses satisfactory properties, such as high mechanical and elastic properties, good electric and thermal conductivities, non-magnetic property and good cold ,wear and corrosion resistances. The properties of beryllium bronze are dependent essentially on the heat treatment process consisting of solution treating and aging. The beryllium bronze parts are to be solution treated in such protective media as wood coal, ammonia- decomposed or alcohol-cracked atmosphere and so on. The aging also is an important heat treatment sequence,including underaging, normal aging, overaging and modified aging processes such as stepped aging and double aging. The chemical composition, microstructures and properties after heat treating with different processes were introduced concerning some commonly used beryllium bronzes.
