Abstract

The Re-Si and Re-B systems were thermodynamically modeled using the Calphad method. The obtained thermodynamic descriptions for the Re-Si and Re-B systems reproduce not only the phase equilibrium but also thermodynamic property data. The Re-Si-B thermodynamic description was then established through extrapolation of binary ones of Re-Si and Re-B developed in this work and B-Si from literature. The calculated Re-Si-B isothermal section at 1200 °C agrees well with experimental data. The calculated ternary liquidus projection predicts the liquid-solid phase equilibria in the Re-Si-B system for the first time, which can be used as a guidance for experimental design of future study.
