· TiAlNi2

TiAlNi2 is a intermetallic compound based on the titanium-aluminum-nickel system, representing a research-phase material combining the lightweight and high-temperature potential of titanium aluminides with nickel strengthening. While not yet in widespread commercial use, this alloy family is of interest in aerospace and power generation sectors where high strength-to-weight ratios and thermal stability are critical; intermetallic compounds like this offer superior stiffness and creep resistance compared to conventional titanium alloys, though they typically exhibit lower room-temperature ductility and require careful processing.
