Abstract

Steels are commonly used metallic materials, that’s why higher requirements are imposed on their properties. Thermodynamical and thermophysical properties are one of the most important quantities of materials, which are needed for understanding behavior of materials under defined conditions. Thermal analysis has been widely used in various scientific fields, it can be used for study thermophysical and thermodynamic properties as well. The aim of the paper is study of six model alloys based on Fe-C-Cr-Ni, which contained carbon in a range of 0.0023 – 0.0095 wt%, chromium 0.0050 – 4.5528 wt% and nickel 0.0020 – 4.9600 wt%. Specific heats and phase transformations temperatures were studied in a high-temperature area. Experimental data were obtained using Setaram MHTC 96 Line with a 3D DSC sensor. Theoretical data were calculated using SW Thermo-Calc and JMatPro, then were compared and discussed with experimental data.

Keywords: Fe-C-Cr-Ni alloys, specific heats, phase transformations temperatures, high temperature area
