THERMAL ANALYSIS AND THEORETICAL CALCULATIONS OF THERMOPHYSICAL PROPERTIES OF FE-C-NI BASED ALLOYS

Popis výsledku v původním jazyce

Three model alloys based on Fe-C-Ni were studied. The alloys containing carbon between 0.338 and 0.382 wt% and nickel between 1.084 and 4.478 wt%. Phase transition temperatures, coefficient of thermal expansion, and density were experimentally and theoretically determined and clarified for all specific alloys in the high-temperature area from 1000 oC to 1595 oC. Phase transition temperatures were experimentally obtained using differential thermal analysis (DTA), differential scanning calorimetry (DSC), and dilatometry. The coefficient of thermal expansion and density were determined by dilatometry. Additionally, experimental data were compared and discussed with calculation results using SW JMatPro, and Thermo-Calc. The obtained experimental results show that with increasing nickel content, the temperature of the liquidus and the coefficient of thermal expansion decrease. Conversely, the density increases with increasing nickel content. The ambiguous influence of nickel on the change in solidus temperature was observed. (C) METAL 2022. All rights reserved.
