The paper deals with numerical model of thermal phenomena and phase transformation in solid state with tempering. To modeling the process heat transfer equation and macroscopic model of phase change based on CCT and CHT diagrams are used. The numerical solution of heat conductivity equation is introduced to estimate the temperature field during the heating and cooling processes. To solve this equation finite element method (FEM) derived on the base of Bubnov-Galerkin formulation is applied.
