· JVASP-102990· TiAu3

TiAu3 is an intermetallic compound combining titanium and gold in a 1:3 atomic ratio, forming a brittle metallic phase with high density and significant stiffness. This material is primarily of research and specialized interest rather than widespread industrial use; it belongs to the titanium-gold intermetallic family explored for potential applications requiring exceptional hardness and chemical inertness, though its brittleness and high cost limit adoption compared to conventional titanium alloys or gold-based systems.
