| Abstract: | The reasons of cracking of Cr12MoV steel in quenching were analyzed. The fracture surface and the metallurgical microstructure were observed by means of SEM and OM.According to the fracture surface and analyses on metallurgical microstructure ,the reasons of cracking of the die steel in quenching are mainly that the grain is coarse and carbide distribution isn't homogeneous. |
