1. The deformation free quenching process is the application of pre cooling isothermal quenching process in tool steel and die steel. The method is to increase the amount of residual austenite through heat treatment process to reduce the quenching deformation, so as to achieve the purpose of deformation free quenching.
2. As we all know, the specific volume of austenite is smaller than pearlite and martensite, so the amount of residual austenite can be increased by increasing the heating temperature, holding the medium temperature isothermal, and pre cooling before isothermal quenching to balance the volume expansion during martensite transformation to reduce quenching deformation.
The introduction of deformation free quenching in this article is over, and I hope it will be helpful to everyone.
