Ti15Al11Ni74

Ti15Al11Ni74 is a titanium-based intermetallic compound with significant aluminum and nickel content, representing a ternary titanium aluminide system. This material family is primarily explored in high-temperature structural applications where lightweight performance and thermal stability are critical, though Ti15Al11Ni74 specifically appears to be a research composition rather than an established commercial alloy. The material's potential lies in aerospace and power generation sectors where reducing component weight while maintaining strength at elevated temperatures drives material development, though it faces competition from more mature titanium alloys and nickel superalloys with better-established processing routes and property reliability.
