Abstract：Refractory alloys possess outstanding high-temperature mechanical properties and radiation resistance, offering broad application prospects in fourth-generation nuclear energy systems. This paper reviews research progress focusing on the effects of processing techniques, alloy composition, and extreme service conditions of the reactor on the fatigue properties and fracture toughness of refractory alloys. It reveals that current research on refractory alloys for reactors has evolved from traditional materials preparation and property characterization to a systematic exploration of the interactions among processing techniques, alloy composition, and service environments. It identifies existing problems in the current research and outlines key future research directions for refractory alloys in reactor applications.
