Modeling of Kinetics and Grain Density Evolution during Isothermal Phase Transformation

Abstract:

Article Preview

On the basis of the proposed analytical phase transformation model, a new modified numerical model is presented to evaluate grain density evolution with only basic kinetics parameters. The proposed model is applicable for phase transformation including random nucleation, growth and impingement under isothermal condition. A two-step fit of the current model to numerical calculation describes the grain density evolution and the transformation kinetics well. Compared with the KJMA model, the modified method is advantageous for application without considering complex and detail transformation process.
