Abstract

Abstract

Thermo-Calc thermodynamic software was used to calculate the phase diagram of 6Cr13Mo stainless steel. The heating, cooling, and solidification processes of 6Cr13Mo stainless steel were simulated via an ultra-high temperature confocal microscope, and the evolution of carbide was observed and analyzed. The results show that the room temperature microstructure of 6Cr13Mo stainless steel calculated by phase diagram is ferrite and M₂₃C₆ type carbides. During the solidification process, the components undergo solidification segregation. The composition system changes into the hypoeutectic steel system when the content of C in the liquid phase reaches about 1%, and M₇C₃ type carbides precipitate directly from the liquid phase while austenite precipitates. During the heating process, the carbide first increases and then decreases with the increase in temperature. During the cooling process, the carbide gradually increases with the decrease of temperature and reaches a peak at 800 ℃. During the solidification process, the number of M₇C₃ decreases, and the morphology changes with the increase in the solidification rate.
