摘要

摘要:发现CZ127在900℃热处理后才能实现完全固溶处理。SST温度的升高并没有改善时效材料的力学性能。采用光学显微镜和透射电镜观察了SST CZ127在200 ~ 700℃时效过程中的显微组织。在所有时效温度下进行600 s热处理后，均发现了复杂的CuNiSi析出物。

Variations in mechanical properties and microstructure of CZ127 (Tungum or Ni–Al–Si α-brass) during aging after solution treatments at 800 and 900°C

AbstractComplete solid-solution treatment (SST) of CZ127 was found to be achieved only after heat treatment at 900°C. The increased SST temperature did not improve the mechanical properties of the aged material. The microstructures of SST CZ127 aged at temperatures between 200 and 700°C were examined using optical and transmission electron microscopy. A complex CuNiSi precipitate was found after 600 s heat treatment at all aging temperatures.
