· JVASP-79540· Ti2MnGa

Ti2MnGa is an intermetallic compound in the titanium-manganese-gallium system, representing a class of lightweight metallic materials with ordered crystal structures. This material belongs to the family of titanium-based intermetallics, which are primarily studied for applications requiring combinations of low density and high-temperature strength; Ti2MnGa remains largely experimental and is not yet established in widespread commercial use, but the titanium-intermetallic family shows promise for aerospace and energy applications where weight reduction and thermal stability are critical.
