Abstract

The thermophysical properties, e.g., melting range, specific heat, solid fraction, density, and surface tension of four industrial Ni-based alloys, namely MC-2, CMSX-10, TMS-75, and LEK-94, have been determined within the ground-based experiments program of the ESA MAP ThermoProp project. The tests were performed under reducing atmosphere in order to lower the oxygen contamination. The results obtained have been compared with the corresponding data of Ni-based alloys available in literature. The new experimental data have been analyzed as a function of both temperature and alloy composition and interpreted by means of different thermodynamic models.
