Thermal analysis of alloys based on Fe-C-Cr in high-temperature area

Popis výsledku v původním jazyce

Three alloys based on Fe-C-Cr were studied. These alloys contained carbon in a range of 0.28 – 0.38 wt.% and chromium 1.06 – 4.99 wt.%. Temperatures of solidus (TS), liquidus (TL) and peritectic transformation (TP) were studied in the high-temperature region. These temperatures were obtained using two thermal analysis methods: Differential Thermal Analysis (DTA) and direct Thermal Analysis (TA). The Setaram Setsys 18TM was used for experiments with the use of DTA method. Measurements were done in an inert atmosphere of pure argon at a heating rate of 10 °C•min-1. The instrument Netzsch STA 449 F3 Jupiter was used for experiments with the use of direct TA method. Measurements were done in an inert atmosphere of pure argon by a heating and cooling rate of 5 °C•min-1. Phase transformation temperatures were obtained by heating and cooling process and they were also approximated to “equilibrium conditions”. The experimental data were compared and discussed with the calculation results using IDS (solidification analysis package), SW Thermo Calc with the use of the TCFE8 (Thermo-Calc Fe-based alloys) database. Two alloys were compared with the published data on similar steels.
