· JVASP-91787· HfAlPt2

HfAlPt2 is a ternary intermetallic compound combining hafnium, aluminum, and platinum, belonging to the class of high-temperature refractory metal alloys. This material is primarily investigated in research contexts for high-temperature structural applications where exceptional thermal stability and oxidation resistance are critical. The platinum addition provides enhanced oxidation protection while the hafnium-aluminum base contributes to creep resistance, making this alloy of interest for aerospace propulsion systems, thermal barrier coatings, and advanced heat-engine components operating at extreme temperatures.
