摘要: The paper deals with theoretical and experimental study of phase transformation temperatures steels in high temperature region (above 1000 °C), focus on the solidus temperature, peritectic liquidus multicomponent steels. Experimental data were obtained using Differential Thermal Analysis “direct” thermal analysis. assessed by basic statistics. calculations performed InterDendritic Solidification software Thermo-Calc software. Also, selected empirically based models used for calculations. presents principles methods, characteristics, advantages disadvantages. Both thermo-analytical methods are set correctly; results reproducible, comparable close to equilibrium temperatures. Furthermore, comprehensive comparisons between calculated measured show that is satisfactorily accounted present thermodynamic description.
