  • The effects of three heat treatment processes of the ZG14CrNi3MoV cast steel microstructure and mechanical properties were compared, which were "single-phase zone quenching+two-phase zone quenching+high temperature tempering", "single-phase zone insulation+slow cooling into two-phase zone+high temperature tempering", "two-phase zone quenching+high temperature tempering". The results show that the two-phase zone heat treatment process has a great influence on the microstructure and mechanical properties of ZG14CrNi3MoV cast steel. The heat treatment process of "single-phase zone quenching+two-phase zone quenching+high temperature tempering" is adopted. The microstructure of cast steel is ferrite and tempered sorbite, and the strength and toughness match well.
