Experimental and theoretical determination of heat capacities of model alloys based on Fe-C-Cr
Original language description
Three model alloys based on Fe-C-Cr were studied. Alloys contained carbon of 0.34 wt% and chromium in a range of 0.92 - 4.76 wt%. Heat capacities were studied in a low and high-temperature region. The experimental heat capacities ("apparent heat capacities") were obtained using Differential Scanning Calorimetry (DSC) with use of a continuous method. The Setaram MHTC (Multi High-Temperature Calorimeter) 96 with a3D DSC sensor was used for experiments with the use of the DSC method. Measurements were done in an inert atmosphere of pure argon by a heating rate of 5oC/min. The experimental data were compared and discussed with the calculation results using SW Thermo-Calc with the use of the TCFE8.1 (Thermo-Calc Fe-based alloys) database. Structural and phase analysis was performed with the use of the Olympus IX70 optical microscope. There is not an unequivocal trend in increase or decrease of experimental heat capacities with increasing content of chromium in the temperature range of 457.15 - 1370.15 K. Experimentally obtained heat capacities decrease with increasing content of chromium except for phase transformations in the temperature range of 1371.15 - 1853.15 K.
