Abstract Scope |
High entropy superalloys (HESAs) have emerged as a promising class of materials due to their excellent mechanical properties, lower densities, and high melting points, making them attractive alternatives to traditional nickel-based superalloys. This study focuses on predicting the phase stability of a γ'-precipitate-strengthened HESA using CALPHAD methodology and comparing the modeling results with experimental data. The effects of alloy composition on the microstructure of HESAs will be investigated using high-temperature X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDS). The influence of compositional changes on the steady-state creep rate of these alloys under compression will be reported. By integrating computational modeling with experimental investigation, this study aims to provide insights into the design of HESAs for enhanced creep resistance. The findings of this study may have important implications for the development of next-generation high-temperature materials for aerospace and energy applications. |
