HfNb2VC4
metal· JVASP-105495· HfNb2VC4
HfNb2VC4 is a high-entropy refractory metal carbide compound combining hafnium, niobium, vanadium, and carbon. This is an experimental material belonging to the ultra-high-temperature ceramic carbide family, developed for extreme thermal and mechanical environments where conventional superalloys reach their limits. The material system shows promise for next-generation aerospace and power generation applications requiring exceptional hardness, thermal stability, and oxidation resistance at temperatures exceeding those handled by traditional nickel-based alloys.
