Summary:•A system analysis of dendritic crystallization.•Thermophysical parameters of process are established by thermodynamic modeling.•Nonequilibrium course of crystallization was studied by computer simulation.•Stage of peritectic transformation of steels in the mesoscale.•Suppression of solid phase diffusion is connected with dendrite arm spacing. The authors present a computer model of the non-equilibrium peritectic transformation in the multi-component alloys Fe-C-∑Xi for the system analysis of phase transformations. The course of the process describes mesoscale equations of heat transfer, phase releasing, and diffusional redistribution of components under the coalescence of a dendritic structure. The simulation results for the rate of formation of the austenitic phase are compared to the literature data.
