EUROPEAN CONGRESS AND EXHIBITION ON ADVANCED MATERIALS AND PROCESSES - EUROMAT 2021

In this contribution, selected key thermophysical and thermodynamical properties of Fe-C-Cr, Fe-C-Ni and Fe-C-Cr-Ni based alloys such as solidus and liquidus temperatures, peritectic transformation temperature and other phase transition temperatures, heats of fusion, specific heat capacities, enthalpies, densities, coefficient of thermal expansion, viscosity, surface tension, wettability expressed by the wetting angle on alumina substrate of liquid alloys were experimentally determined in a high-temperature area up to the temperature of 1600 °C. The effect of the temperature and chemical composition of alloys on these properties was investigated using 3D heat flux DSC, DTA, dilatometry, sessile drop and viscosity method. The interaction of the studied alloys with the alumina substrate was studied by SEM, EDX, and XRD methods. To assess the influence of the major elements (carbon, chromium, and nickel), the alloys with different carbon, chromium and nickel content varied in the range of 0-1.5 wt.%, 0 5 wt.% and 0–5 wt.%, were chosen.
