· JVASP-37058· Ti2AlCu

Ti2AlCu is an intermetallic compound combining titanium, aluminum, and copper—a lightweight metallic phase that forms within titanium-aluminum alloy systems. This material is primarily encountered as a constituent phase in advanced titanium alloys rather than as a monolithic engineering alloy, where it contributes to strengthening mechanisms through precipitation hardening in aerospace and high-temperature applications. Its presence is notable in titanium-aluminum-copper alloy development for improving creep resistance and high-temperature strength compared to binary titanium-aluminum systems, though engineering use is typically managed through careful alloy design and heat treatment rather than direct application.
