· JVASP-39689· Ti2ReIr

Ti2ReIr is an intermetallic compound combining titanium with rhenium and iridium, belonging to the family of refractory metal alloys designed for extreme-temperature and high-strength applications. This material exists primarily in research and development contexts, where it is investigated for potential use in aerospace propulsion systems, nuclear reactor components, and other environments requiring exceptional thermal stability and oxidation resistance. The addition of refractory elements (rhenium and iridium) to titanium matrices aims to extend operating temperatures well beyond conventional titanium alloys while maintaining structural integrity, making it a candidate for next-generation high-performance applications where cost and manufacturability constraints are secondary to performance demands.
