Along with the globalization of environmental problems and the rapid development of the field of nuclear technologies, the severe irradiation damage of materials has become a big issue, restricting the development of advanced nuclear reactor systems. Refractory high-entropy alloys (RHEAs) have the characteristics of a complex composition, a short-range order, and lattice distortion and possess a high phase stability, outstanding mechanical properties, and excellent irradiation resistance at elevated temperatures; thus, they are expected to be promising candidates for advanced nuclear reactors. This review summarizes the design, preparation, and irradiation resistance of irradiation-tolerant RHEAs. It encompasses a comprehensive analysis of various aspects, including the evolution of defects, changes in microstructure, and the degradation in properties. Furthermore, the challenges and insufficiently researched areas regarding these alloys are identified and discussed. Building on this foundation, the review also provides a forward-looking perspective, outlining potential avenues for future research.

“…In addition, the study in [107] proposed optimizing the laser cladding process parameters through intelligent system optimization algorithms. Cladding can also be achieved through the use of transition layers [108], and the process itself can lead to the creation of functionally graded materials [109] and refractory high-entropy alloys with distinct microstructures and properties [110,111]. The application of laser cladding for the fabrication of high-entropy alloys is thoughtfully presented in [112,113].…”

Refractory high-entropy films (RHEFs), as multi-component materials, have garnered significant attention due to their potential use in high-temperature applications. RHEFs are endowed with unique microstructural and functional properties due to the use of refractory elements. In this review, we examine the recent state of research on RHEFs deposited by the magnetron sputtering technique. The microstructure of RHEFs has been analyzed/explored and the mechanical properties as well as the main hardening mechanisms of these films are discussed. Furthermore, functional properties such as resistance to corrosion and wear, electrical and irradiation performances, and high-temperature oxidation were evaluated. RHEFs can meet market demand in the field of engineering materials. However, many challenges, such as low ductility at room temperature, remain to be overcome. This review provides an overview of the strengths and weaknesses of RHEFs produced using magnetron sputtering.
