Microstructure and Thermal Plasticity of Semi-Solid M2 Steel Casting Ingots Using Inclined Slope Pre-Crystallization Method

Abstract:

Semi-solid M2 steel casting ingots were prepared using inclined slope pre-crystallization method, and the microstructure at different slope length and thermal plasticity of ingots were investigated in this paper. It was clarified that semi-solid processing technology can solve the serious problem of eutectic carbides segregation in casting microstructure. The dendritic primary austenite grains are changed into non-dentritic or equiaxed grains, and the eutectic ledeburite carbide networks are fine. So, it improves the thermal plasticity of casting ingots, and the carbide distribution of the semi-solid casting ingots is better than conventional casting after being forged.
