Titanium Aluminides (TiAl, Ti₃Al, TiAl₃, Ti-48Al-2Nb-2Cr, Ti2AlNb)
TiAL has excellent mechanical properties as well as oxidation and corrosion resistance at elevated temperatures (over 600 degrees Celsius).
TiAl₃ has the lowest density, the highest microhardness, and the best oxidation even at high temperatures but has poor ductility, which may limit its use.
Ti₂AlNb alloy has high-temperature strength, good anti-oxidation properties, and low density. It has shown long-term service temperatures of up to 923 K–973K
Ti-48Al-2Cr-2Nb- has an excellent strength-to-weight ratio, almost as light as aluminum but more strength than most steel alloys. It has superb corrosion resistance and very low heat conductivity, and high flexibility.
Powder available as small as 10 microns average particle size
Titanium Aluminides compete with Nickel superalloys for the fabrication of aircraft frames and engine parts as well as in some automotive applications (exhaust valves and turbochargers). Other applications include investment casting, wire/fiber metal matrix composites, and in intermediate processing for some mill products.
