摘　　要：对45Mn2钢球的热处理工艺和力学性能进行了研究。结果表明:在锻造余热淬火的条件下,随着回火温度的升高,抗拉强度降低,冲击韧性增大;淬火后的显微组织是板条马氏体,其耐磨性能优于45钢和中锰铸铁。The heat treaUnent process and mechanical properties of 45Mn2 steel ball were studied. The results show that under the condition of forging residual heat quenching, the tensile strength decreases and the impact toughness increases with the increase of the tempering temperature. The microstructure after quenching is lath martensite, and its wear resistance is better than that of 45 steel and medium manganese cast iron.
