“…The slow strain rate test experiment shows that embrittlement mostly occurs at lower temperatures, that is, between 140-425 • C [88]. When the temperature is further raised above 500 • C, its ductility recovers [89]. Another important factor is whether the oxide film is formed or not.…”

In order to meet the growing energy demand, more environmentally friendly and efficient GEN-IV reactors have emerged. Additionally, nuclear structural materials need larger more safety margins for accident scenarios as a result of the Fukushima accident. In order to extend the failure time and lessen the effect of accidents, this design method for accident-tolerant fuel materials calls for cladding materials to maintain good corrosion resistance and mechanical properties during a beyond design basis accident (BDBA). Accidents involving nuclear reactors would undoubtedly result in higher temperatures, which would make it much harder for materials to withstand corrosion. Oxide dispersion strengthened (ODS) FeCrAl alloys have shown promise as candidate materials because of their extraordinarily slow reaction rates under high-temperature steam. However, the addition of the Al element renders the alloy’s high-temperature mechanical properties insufficient. In particular, studies on the alloy’s creep properties are extremely rare, despite the fact that the creep properties are crucial in the real service environment. Therefore, this paper focuses on the creep properties of ODS FeCrAl alloy, summarizes and analyzes the research results of this material, and provides a reference for future research and applications.

“…An increase in Al content can make FeCrAl more susceptible to LME than an increase in Cr content [621]. The strong LME effect in FeCrAl alloys was attributed to Al-induced solid solution strengthening and the probably more brittle nature of the Al-enriched oxides, while the ductility of the Fe10Cr4Al alloy in LBE recovered fully at 500 • C [622]. These results indicate that Al-rich oxide scales cannot sustain high tensile stresses so as to fully prevent LME in FeCrAl alloys [562], which is unfortunate as these materials possess an excellent LMC resistance.…”

“…In view of the porous nature of nuclear graphite, the infiltration of molten LBE into the graphite coolant channels is a significant concern. Moreover, molten LBE has been shown to be highly corrosive of structural materials such as high-entropy alloy [2] and ferritic alloy [3], so the corrosion of the graphite coolant channels is a significant concern too, although nuclear graphite has high chemical stability and high temperature mechanical strength. For the development of CHTR, it is necessary to study the infiltration behavior and chemical compatibility of molten LBE in commercial nuclear graphite at elevated temperature.…”
