V5Si3
metalV5Si3 is a vanadium silicide intermetallic compound belonging to the refractory metal silicide family, valued for its exceptional high-temperature strength and oxidation resistance. This material is primarily investigated for ultra-high-temperature aerospace applications such as turbine engines, hypersonic vehicle structures, and thermal protection systems where conventional superalloys reach their performance limits. V5Si3 represents an emerging class of materials rather than a widely commercialized product; its potential lies in enabling operation at temperatures significantly above current nickel-based superalloys while maintaining structural integrity, though manufacturing, brittle-to-ductile transition, and cost remain active research challenges.
