Application of Computer Simulation to Study the Features of the Austenite Isothermal Transformation in Steels
Abstract
An algorithm was developed for the simulation of a phase transition in solid state which makes it possible to obtain the kinetic curves of transformation under different initial conditions (the number and arrangement of new phase nuclei, the distance between the nearest nuclei). The simulation results were analyzed using the KolmogorovJohnson-Mehl-Avrami equation and the corresponding coefficients were determined. The correlation between the simulation results and the experimental kinetics of the austenite isothermal transformation in alloyed steels was shown.
Keywords: computer simulation; modeling; phase transformation; kinetics; KJMA equation; logistic function; steel.
