Application of Computer Simulation to Study the Features of the Austenite Isothermal Transformation in Steels


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 Kolmogorov-

Johnson-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.
