| Abstract: | The effect of preheating of carbide refining and homogenizing and the effect of common pretreating of annealing upon microstructures of mould steels,distortion resulted from quenching and temperting,impact toughness of quenched and tempered samples have been analysised and compared.The results show that the pretreating of carbide refining and homogenizing will refine and homogenize carbide in the steels,obviously decrease the distortion resulted from quenching and tempering and increase the service life of mould. |
