“…The researches of Nb-containing FeCrAl regarding oxidation, corrosion, and mechanics have been conducted to demonstrate their potential as advanced cladding materials [ 5 , [23] , [24] , [25] ], but the irradiation experiment data of these alloys remains limited at present. Traditionally, the phase boundary is considered the efficient sink for radiation-induced defects, though high-dose irradiation, the stability of the Laves phase precipitate may become a problem.…”
