Краткое описание

A comparison of various approaches to modeling of phase transformations during heat treatment of steels is the objective of the paper. The first approach is a conventional model based on the Avrami-type equation. In this approach, the Avrami coefficients are introduced as the modified Gauss distribution function of temperature. This model is identified using inverse analysis applied to the dilatometric tests. The model with optimized parameters is implemented into the finite element code, which simulates heat treatment of steel parts. The second approach is a coupled finite element-cellular automata (CAFE) multiscale model, which accounts explicitly for the phenomena occurring during transformations in the microscale. Simulations using both models were performed and the results were compared. Advantages of the CAFE model, as far as predictive capabilities and efficiency are concerned, are presented in the final part of the paper.
