TiAl is a new class of aerospace alloys that offers an excellent strength-to-weight ratio as well as high chemical and thermal stability. Gamma titanium aluminide alloy has excellent mechanical properties as well as oxidation and corrosion resistance at elevated temperatures (over 600 degrees Celsius). TiAl is the latest class of materials competing with Nickel superalloys for the fabrication of aircraft engine parts such as low-pressure turbine.
