Abstract

Based on an extended Johnson-Mehl-Avrami-Kolmogorov analytical phase transformation kinetics model, new recipes and an iterative approach were proposed to determine non-isothermal kinetic parameters including anisotropic impingement parameter ξ, growth exponent n, activation energy of nucleation QN, activation energy of growth QG, temperature independent nucleation rate N0 and number of pre-existing nuclei per unit volume N* etc. Numerical examination approves the validity of the new approach by its better accuracy.
