TiAlAu is a ternary intermetallic alloy combining titanium, aluminum, and gold, representing an experimental composition in the titanium-aluminum family of materials. This material is primarily of research interest, as it combines the lightweight and high-strength characteristics of titanium-aluminum intermetallics with gold's exceptional corrosion resistance and biocompatibility—a combination not typically found in commercial alloys. The inclusion of gold makes TiAlAu a candidate for specialized applications where corrosion immunity and biological tolerance are critical alongside mechanical performance, though its use remains limited to investigation in academic and advanced materials development settings.
