The utilisation of next-generation superalloys is of utmost significance in the progression of contemporary engineering applications that necessitate extraordinary mechanical strength, stability at elevated temperatures, and resistance to corrosion. The present work aims to conduct a thorough investigation of the microstructural and mechanical properties of these advanced materials, providing insights into their distinct features and possible areas of application. The examination of microstructure involves the utilisation of several methodologies, including scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD). The present study comprehensively examines the complicated grain structures, phase compositions, and distribution of strengthening precipitates inside the superalloys using various methodologies. The correlation between processing factors and resultant microstructures is established, facilitating a more profound comprehension of the influence of microstructure on the mechanical properties of the alloy. The knowledge acquired from this investigation into the microstructural and mechanical characteristics of next-generation superalloys provides useful insights for engineers, researchers, and designers engaged in materials development and component design. Through the use of a comprehensive comprehension of the distinctive properties of these alloys, it becomes feasible to expand the limits of performance in exceedingly challenging conditions, so influencing the trajectory of high-temperature engineering applications in the future.

“…[5] Furthermore, the BCC HEA is considered a promising option for aero engines, nuclear reactors, and gas turbines in the future, due to the high melting points employed metals and hysteretic diffusion. [6][7][8][9] The main challenge that limits the application of metallic materials at high temperatures is creep. The creep break is always sudden, and it can be incredibly deadly for hightemperature components, making it even worse.…”

The BCC high entropy alloy (HEA) has always been considered a promising material for high temperatures, and a novel BCC HEA was developed in this study. The precipitation of a second HCP phase in the grain during the warming process is responsible for the alloy's characteristic high temperature strength. The dynamic modulus of the alloy increased continuously above 550°C, while its internal friction peak exhibited the typical signature of a grain boundary peak. Annealing at 800°C for 3 hours has the potential to slightly enhance ductility and reduce room temperature compression strength to a limited extent. It is believed that the initial decrease and subsequent increase in dynamic modulus can be attributed to the combination of second phase precipitation and thermal relaxation. The TEM and fracture SEM analysis of heat-treated specimens revealed that the modification of high temperature hardening and ductility was attributed to the second phase, which impedes the dislocation's movement.
