Ti5Re24

Ti5Re24 is a titanium-rhenium alloy containing approximately 5% titanium and 24% rhenium, representing a high-density refractory metal composite designed for extreme-temperature applications. This alloy is primarily investigated for aerospace and defense applications where conventional superalloys reach their performance limits, particularly in rocket engines, hypersonic vehicle structures, and next-generation jet propulsion systems where exceptional strength retention at elevated temperatures is critical. The rhenium addition significantly improves high-temperature creep resistance and ductility compared to pure refractory metals, making it notable for engineers working on materials that must perform in the 1200–1600°C range where nickel superalloys become inadequate.
