Background

Quenching is a heat treatment process for heating a casting to a temperature above a critical temperature at a proper speed, preserving heat for a period of time to complete austenitization, and then cooling at a cooling speed higher than the critical cooling speed to avoid a pearlite transformation region, thereby obtaining a non-equilibrium structure mainly comprising martensite or bainite.
