Quenching, a heat treatment process for metals and glass. Alloy products or glass heated to a certain temperature, and then in water, oil or air rapid cooling, generally used to improve the hardness and strength of the alloy. Commonly known as “dip fire. “. Heat treatment of metal cooled in air or water or oil […]
Quenching is the process of heat treatment to obtain the martensite structure by heating the metal or parts above the phase change temperature and then rapidly cooling them beyond the critical cooling rate. Quenching is to obtain the martensite structure, and after tempering, the workpiece to obtain good performance, in order to give full play […]
The microstructure obtained by high-temperature tempering is tempered sorbite. The main purpose of tempering is to eliminate quenching stress and get the required structure. According to the different tempering temperature, tempering can be divided into a low temperature, medium temperature, and high temperature. Tempered Martensite, troostite, and sorbite were obtained.
