Název v původním jazyce

Determination of thermodynamic properties of alloys based on Fe-C-Cr with use of thermal analysis methods and theoretical calculations

Popis výsledku v původním jazyce

In this work were described thermal analysis methods - DTA, DSC and continuous method. Calculations with the use of theoretical relationships and SWs based on CALPHAD and Phase Field method were used. Phase diagrams of Fe-Fe3C and Fe-Cr-C (with 5 wt. % of Cr) were calculated with SW Thermo-Calc. As an experimental material were 3 model alloys based on Fe-C-Cr with the same content of carbon (0,34 wt. %) and content of chromium 0,92 - 4,76 wt. %. Temperatures of phase transformations and heat capacities were obtained. For temperatures of phase transformations were used device Setaram Setsys 18TM and for obtaining heat capacities was used device Setaram MHTC 96 Line. Experimental results were compared with theoretical results calculated by SW Thermo-Calc and IDS.
