Abstract Scope |
The medium entropy alloys based on Ni were created using Thermocalc software and produced through arc suction casting, with Ti-guttering in an argon environment. The impact of adding Cu on phase development, microstructure, and mechanical properties was examined. A detailed analysis revealed that the alloys demonstrate a dual microstructure, comprising BCC dendrites and FCC interdendrites in the N4 alloy, whereas the Cu-added N6 alloy exhibits a rectangular morphology with γ + γ՛ phases. Mechanical property tests indicated exceptional strength at high temperatures compared to Inconel 713C, coupled with excellent ductility in the presence of the γ + γ՛ phase microstructure. Various alloy design methods, including composition-based models and predictive techniques, aim to find suitable compositions. Certain non-equiatomic multi-component Medium Entropy Alloys (MEAs) show uncomplicated solid structures and impressive strength, similar to equiatomic quaternary and quinary alloys. |
