High-temperature structural materials face severe degradation challenges due to oxidation and corrosion, leading reduced long-term stability performance. This review comprehensively examines the interfacial migration mechanisms of reactive elements (REs) such as Ti, Al, Cr in Ni/Fe-based alloys, emphasizing their role forming stabilizing protective oxide layers. We discuss how these layers impede ion mitigate environmental degradation. Key findings highlight importance selective oxidation, layer healing, integration novel alloying enhance resistance under ultra-supercritical conditions. Advanced insights into grain boundary engineering, alloy design strategies, quantum approaches understanding charge transport at passive interfaces are also presented. These provide a foundation for developing next-generation high-temperature alloys with improved tailored withstand extreme
