· Ti4Al25Ni21

Ti4Al25Ni21 is an intermetallic compound in the titanium-aluminum-nickel (Ti-Al-Ni) system, likely an experimental or specialized composition combining titanium's strength and corrosion resistance with aluminum's lightness and nickel's toughness-enhancing properties. This material family is investigated primarily for high-temperature structural applications where weight reduction and thermal stability are critical, though Ti-Al-Ni intermetallics remain largely research-focused rather than commodity production. The specific stoichiometry suggests potential for aerospace or automotive applications where conventional titanium alloys or nickel superalloys fall short of combined performance targets.
