Phase Composition Of T10 Steel During Gas Quenching

Heat treatment is one method to improve mechanical properties of metal, but each heat treatment method has its advantages and disadvantages, therefore, different requirements regarding size, shape, and properties with respect to different heat treatment processes should be considered. Gas quenching is a relatively new process with several important advantages, such as minimal environmental impact, clean products, and ability to control the cooling locally and temporally for best product properties. To meet the high cooling rates required for quenching, the cooling gas must flow at very high velocities. The phase transformation will occur during quenching. The phase composition will influence the mechanical properties of metal. Consequently, the computation of phase composition is important for the mechanical properties of metal after quenching. In this paper, the mathematical model of phase composition computation was created based on phase transformation kinetics, The phase composition of T10 steel during gas quenching was calculated.
