Common processes include forging preheating quenching, solid solution double refining process, cooling quenching, and isothermal quenching. Among them, the solid solution double refining treatment is a method of heat treatment to refine the carbide, round the corners, and at the same time make the austenite grains ultrafine. The main measures of the process are high temperature solid solution and cycle refinement. High temperature solid solution can improve the morphology and particle size of the carbide; the purpose of the cycle refinement is to make the austenite grains ultra-fine.
