| Abstract: | To improve the heat processing parameters in cold-punching mold manufacturing with high-speed steel W18Cr4V,the quenching temperature,tempering temperature,tempering times and influence of the volume of retained austenite on surface hardness and roughness of the material are researched.The results indicate that the volume of retained austenite in W18Cr4V changes with the change of quenching temperature and tempering temperature.The relation between the surface hardness and the volume of retained austenite c... |
