摘　　要：对W6Mo5Cr4V2Al合金钢进行了普通正火、等温正火和锻造余热正火的热处理试验,研究不同热处理工艺对W6Mo5Cr4V2Al齿轮钢的组织和硬度的影响。结果表明,冷却速度的增加和等温温度的降低使贝氏体含量增加,材料的硬度增大。The heat treatment experiments of ordinary normalizing, isothermal normalizing and the residual forging heat normalizing after forging of W6Mo5Cr4V2A1 were conducted and effects of different heat treatment process on the microstructure and hardness of W6Mo5Cr4V2A1 Gear steel were studied. The results show that the content of bainite increases and the hardness increases with the increase of cooling velocity and the decrease of isothermal temperature.
