Optimization Decomposition Cast Structure in M35 High-Speed Steel

Abstract:

The effects of the different heat-treatments on the eutectic carbides in HSS cast strip are studied. The microstructure of the high speed steel(HSS) is analysized by means of optical microscopy and SEM. The results show that the heat treatment can make M2C and M6C metastable phase decompose. After comparison we can find that the optimized heat treatment processing of HSS cast strip is at 1200°Cfor 6 h, under which the fine and uniform carbides can be obtained.
