| Abstract Scope |
High temperature oxidation of metallic alloys is inevitable during service. However, aerospace and aeronautical components demand delayed oxidation kinetics of alloys used in them to avoid their sudden failures during service. In line of that, here we present a next generation Ni-Co-V-Fe-Cr-Si containing high entropy alloy (OR-HEA) displaying very sluggish oxidation kinetics after exposing to 1050 C up to 100 hrs in muffle furnace atmosphere. The weight gain appears to saturate at 10 hrs of exposure and showed negligible increase in weight even after 100 hrs of exposure to 1050 C. The resultant high temperature oxidation behavior is exceptional when compared with the conventional IN-718 super alloy and much better than the newly designed refractory containing HEAs in similar temperature range and corrosive atmospheres. Thus, development of OR-HEA is not only providing cost friendly but also weight-effective pathway for designing high temperature alloys of future. |
