核用难熔高熵合金的研究进展

Search of nuclear structural materials with excellent comprehensive properties is one of the significant challenges in advanced reactor development. Refractory high entropy alloys (RHEAs), which have bodycentered cubic structures and contain multiple refractory elements as major alloying elements, have great advantages on irradiation tolerance and high-temperature strength, and thus are promising candidates for nuclear structural materials. In this review, the research progress of RHEAs for nuclear applications is summarized from aspects of alloy design and fabrication, phase structure and phase stability, mechanical property, corrosion resistance, as well as radiation resistance. The future research directions and potential nuclear application scenarios of RHEAs are also presented.
