Thermo-Calc software package (TCP + DICTRA) was used to simulate the carbide transformation process in die steel for plastic. Combined with TEM analysis, the calculated result confirms that the carbide in equilibrium state is M7C3 carbide. The dissolution of M7C3 carbide in steel is predicted by DICTRA program. It was shown that the temperature remarkably affects the dissolution process Of M7C3 carbide, but the influence of alloy elements such as manganese and molybdenum can be neglected in this steel.
