Temperatures of liquidus, solidus and peritectic transformation of Fe-C-Cr based alloys

Popis výsledku v původním jazyce

Three alloys based on Fe-C-Cr were studied. These alloys contained carbon in a range of 0.31 - 0.38 wt.% and chrome 1.06 - 4.99 wt.%. Temperatures of solidus (TS), liquidus (TL) and peritectic transformation (TP) were studied in high temperature region. These temperatures were obtained using two thermal analysis methods: &quot;Direct&quot; Thermal Analysis (TA) and Differential Thermal Analysis (DTA). The Setaram Setsys 18TM was used for experiments with use of DTA method. Measurements were done in inert atmosphere of pure argon by heating rate of 10 oC.min-1. The Netzsch STA 449 F3 Jupiter was used for experiments with use of &quot;direct&quot; TA method. Measurements were done in inert atmosphere of pure argon by heating and cooling rate of 5 oC.min-1. Phase transformation temperatures were obtained by heating and cooling process. Experimental data were compared and discussed with calculation results using IDS (Solidification analysis package) and SW Thermo Calc with use of the TCFE8 (Thermo Calc Fe-based alloys) database. Temperatures of solidus (TS), liquidus (TL) and peritectic transformation (TP) were obtained. Difference between experimental and theoretical values temperatures of liquidus was relatively low. With increasing content of carbon and chrome grew the difference between theoretical and experimental values by temperature of solidus and peritectic transformation.
