Abstract

In this work, the thermodynamic parameters and phase diagrams of some high-entropy ceramics systems (carbide and boride) have been calculated. The analysis allowed us to determine the optimal system: HfZrTiTaNb for synthesizing high-entropy carbide and boride. It was found that this composition has the smallest difference of interatomic distances 4.24 %, low value of enthalpy of mixing 2.64 kJ/mol and high thermodynamic parameter, which takes into account the average melting point of elements, enthalpy and entropy of mixing 12.78.
