摘　　要：研究了热处理工艺对W6Mo5Cr4V3Co8高速钢显微组织和硬度的影响。结果表明,不同截面方向和不同尺寸规格的高速钢显微组织都具有高度的一致性。其淬火温度范围较宽,并且淬火后均匀细小的碳化物颗粒阻碍了奥氏体晶粒的长大。高温回火后,高速钢呈现出明显的二次硬化特征。The effect of heat treatment process on the microstructure and hardness of high speed steel W6MoSCr4V3Co8 was investigated. The results show that the microstructures of the steels with different section direction, size and shape are quite uniform. The quench scale of the steel is wide, and the uniform fine carbide particles block the growth of austenitic grain after quenching. And the high speed steel shows obvious secondary hardening characteristic after tempering at high temperature.

关 键 词：高速钢材料 热处理 淬火
