· JVASP-36231· Ti2Al

Ti2Al is an intermetallic compound in the titanium-aluminum system, representing a ordered phase that forms at specific compositional ratios. This material is primarily of research and developmental interest rather than widely established in production, with potential applications in high-temperature aerospace systems where lightweight, high-strength materials are critical. Its significance lies in exploring alternatives to conventional titanium alloys by leveraging the lower density and potentially enhanced high-temperature stability of titanium-aluminum intermetallics, though brittleness and processing challenges remain limitations compared to conventional wrought titanium alloys.
