摘　　要：用新研制的Ｍ２Ｓｉ－３及Ｍ２Ｓｉ－４研究了热处理对高速钢红硬性的影响．结果得出,提高淬火温度以增加溶入奥氏体中的碳化物以及在淬火后增加一次低温回火均可有效提高红硬性．但为通过淬火温度以提高红硬性．除必须提高钢料碳含量外还应设法细化碳化物．The effects of heat treatment on red hardness of newly produced M2Si-3 and M2Si-4 high speed steels are studied. The results show that the red hardness can be effectively enhanced by increasing quenching temperature to promote carbide to dissolve into austenite and increasing once more tow-temperature temper after the quenching. However, in order to improve the red hardness by increasing quenching temperature, the carbon content must be increased, and the carbide must be fined as well.
