· JVASP-102340· HfWC2

HfWC2 is a refractory metal carbide compound combining hafnium and tungsten carbide phases, belonging to the family of ultra-high-temperature ceramic carbides. This material is primarily of research and development interest for extreme thermal and mechanical applications where conventional superalloys reach their limits, offering potential advantages in oxidation resistance and hardness at elevated temperatures compared to single-phase carbide systems.
