| Abstract Scope |
High entropy superalloys (HESAs) are gaining attention as a promising class of materials, thanks to their impressive mechanical properties, lower densities, and high configurational entropy. These qualities render them appealing substitutes for conventional nickel-based superalloys. This study focuses on the effect of compositional changes on the microstructure and creep resistance of high entropy superalloys through an integrated experimental and computational study. The effect of alloy composition on the microstructure and elemental distribution of HESAs are investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDS). To enhance creep resistance, we adjust the nickel and cobalt content and perform solution and aging heat treatments at temperatures predicted by calculation of phase diagrams (CALPHAD) modeling. By understanding the effect of compositional changes this study aims to provide insights into the design of HESAs with enhanced creep resistance for aerospace and energy applications. |
