Abstract:

Physical basis for modelling of phase transformation during heating of DP steels is given in the paper. Basic models are discussed briefly. The model based on the solution of the diffusion equation with moving boundary was selected as an alternative with extensive predictive capabilities, which include determination of the carbon segregation in the austenite. The diffusion equation was solved using finite difference method for 1D domain and finite element method for 2D domain. Model was validated qualitatively by comparison the results with the dilatometric tests data and good agreement was obtained.
