Hf3TiV8
metal· JVASP-143197· Hf3TiV8
Hf3TiV8 is a refractory high-entropy alloy (HEA) composed of hafnium, titanium, and vanadium in a multi-principal-element system. This material belongs to the emerging class of compositionally complex alloys designed to achieve high strength and thermal stability through entropy-driven solid-solution strengthening rather than traditional precipitation hardening. While primarily a research-phase compound, Hf3TiV8 represents the potential of refractory HEAs to operate in extreme environments where conventional superalloys reach their limits, making it relevant for high-temperature structural applications requiring both strength and oxidation resistance.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
