Determination of heat capacities and carbides alloys based on Fe-C-Cr

Popis výsledku v původním jazyce

Two alloys based on Fe-C-Cr were studied. Alloy A contained carbon of 0.410 wt. % and chromium of 1.083 wt. %. Alloy B contained carbon of 0.430 wt. % and chromium of 4.980 wt. %. Heat capacities and carbides were studied in the low temperature region. The heat capacities were obtained using Differential Scanning Calorimetry (DSC). The Setaram MHTC (Multi High Temperature Calorimeter) 96 with 3D DSC sensor was used for experiments with the use of DSC method. Measurements were done in inert atmosphere of pure argon by a heating and cooling rate of 5°C min-1. The experimental data were compared and discussed with the calculation results using SW Thermo Calc with the use of the TCFE8 (Thermo-Calc Fe-based alloys) database. On the DSC were observed of heat capacities of M7C3, M23C6 carbides and Sigma phase formation, which was supported by calculation of presence of mentioned phases as a function of temperature in SW Thermo-Calc.
