HfAlFe
metal· JVASP-143198· HfAlFe
HfAlFe is a ternary intermetallic alloy combining hafnium, aluminum, and iron, belonging to the class of high-temperature metallic compounds. This material is primarily investigated in research contexts for applications requiring exceptional thermal stability and oxidation resistance, with potential use in aerospace and high-temperature structural applications where conventional superalloys face limitations. The hafnium content provides enhanced refractory characteristics, while the aluminum and iron constituents contribute to strength and processability, making it of interest for next-generation engine components and thermal barrier systems.
