Abstract: The study conducts numerical analyses to examine the effects of chemical composition and temperature on the thermodynamic stability of phases and the kinetics of precipitation processes in INCONEL 800HT alloy. The findings elucidate phase stability trends, precipitation mechanisms, and radiation-induced modifications, contributing to the optimization of alloy performance in high-temperature environments.

Keywords: INCONEL 800HT, CALPHAD method, Phase stability, Precipitation kinetics, Thermodynamic modelling, High-temperature alloys.
