Nb- and Ta-doped (Hf,Zr,Ti)C multicomponent carbides with enhanced oxidation resistance at 2500 °C
Enhancing oxidation resistance of multicomponent carbides above 2000 ℃ is critical for their thermal protection applications. For this purpose, novel Nb- and Ta-doped (Hf,Zr,Ti)C multicomponent carbides were designed to improve their oxidation resistance
