Abstract

This paper presents the results of phase composition calculating by the CALPHAD method using the Thermo-Calc software package for thermodynamic calculations of high-entropy carbides (TiZrHfTaNb)C, (TiZrHfTaNbW)C, (TiZrHfTaNbMo)C. The starting materials lattice parameters influence the possibility of high-entropy carbides single-phase solid solutions formation. A comparative analysis of lattice parameters influence and phase diagrams was carried out. An increase in the difference between the lattice parameters decreases the homogeneity region of carbide solid solutions with the crystal structure of rock salt (NaCl).

Keywords: High entropy alloys, carbides, Thermo-Calc, phase diagrams
