| Abstract: | By analizing the failure cause of 3Cr2W8V pressure casting die in pressure casting aluminum motor rotator, the property requirements were given in this paper. By testing а K and K IC of the specimen after heat treatment, an advanced heat treating process and gas carbonitriding process with catalyst accelerator of iodine was found. It proved that the life of pressure casting die was increased after treating with this new advanced procdss. |
