Modeling Phase Transformations and Material Properties Critical to Processing Simulation of Steels

This article describes the development of JMatPro, a computer software that can provide many of the material properties required by processing simulation. The success of the model is based on accurate description of all major phase transformations taking place, as well as calculation of the properties of different phases formed during the heat treatment process. Predictive phase transformation models in the past mainly concerned carbon and low alloy steels. An advantage of the current model is that it can be applied to many types of steels, including medium to high alloy types. In addition to TTT/CCT diagrams, a wide range of physical, thermophysical, and mechanical properties, including strength and stress-strain curves, can be calculated.
