Exploring high entropy alloys: A review on thermodynamic design and computational modeling strategies for advanced materials applications.

In the quest for materials that can withstand the rigors of modern engineering applications, high-entropy alloys (HEAs) have emerged as a frontier in material science owing to their unprecedented combination of properties. This review focuses on intricate thermodynamic and computational modeling to guide the design and optimization of HEAs. By dissecting the foundational "four core effects" intrinsic to HEAs-high entropy, sluggish diffusion, severe lattice distortion, and cocktail effect-we illuminate the path towards predictable and tailored material properties.

Phase prediction, microstructure, and mechanical properties of spark plasma sintered Ni-Al-Ti-Mn-Co-Fe-Cr high entropy alloys.

The effect of mechanical alloying on the development of Ni-Al-Ti-Mn-Co-Fe-Cr high entropy alloys (HEAs) utilizing the spark plasma sintering (SPS) method is the main goal of this study. A bulk sample was fabricated using SPS after the alloys were mixed for 12 h. Thermodynamic simulation, X-ray diffraction, scanning electron microscopy, nanoindentation, and microhardness were used to investigate the microstructure and mechanical properties of the as-mixed powders.
