摘　　要：对ZG40Mn2铸钢进行了不同工艺的热处理,分析了钢力学性能的变化。研究了不同处理工艺对ZG40Mn2钢调质后力学性能的影响。结果表明:在扩散退火+正火预处理后820℃淬火+580℃回火处理,可以显著提高ZG40Mn2钢的综合性能。The heat treatment of ZG40Mn2 cast steel was carried out by different processes. The changes of mechanical properties of the steel are analyzed. The effects of different treatment processes on the mechanical properties of ZG40Mn2 steel after quenching and tempering were studied. The results show that the treatment of diffusion annealing ＋ normalizing pretreatment and then quenching at 820 ℃ ＋tempering at 580 ℃ can significantly improve the comprehensive performance of ZG40Mn2 steel.
