Two-dimensional approach to the analysis of phase transformation kinetics in steel hardening processes

The paper presents a method for determination of a phase traasformation kinetics in cylindrial steel bodies with an arbitrary shaped cross-section. The analysis is presented for a two-dimensional region, where the heat flow on the edges of the region appears. The solution of the problem is based on variational-difference method, being a combination of the finite element method and the finite difference method. The results are the basis for evaluation of temporary and residual stress distribution in self-cooling processes.
