TiAl9Ni10

TiAl9Ni10 is an intermetallic compound based on titanium aluminide (TiAl) with approximately 9% aluminum and 10% nickel additions, belonging to the class of lightweight, high-temperature intermetallic alloys. This material is primarily investigated in aerospace and power generation sectors where high strength-to-weight ratios and thermal stability are critical, offering potential advantages over conventional titanium alloys and nickel superalloys at elevated temperatures. While still largely in research and development rather than widespread commercial production, TiAl-based intermetallics like this composition are being developed to reduce density and improve creep resistance in engine applications where conventional materials reach their performance limits.
