Abstract
The influence of tempering process on microstructure and hardness of cast-in high speed steel was studied.The experiment results show that microstructure of cast-in high speed steel divided into troostite and incontinuity network carbide,troostite and network carbide,martensite and network carbide with tempering temperature at 700℃,800℃,900℃.The carbide grain can become coarse with increasing tempering temperature.
