High specific strength, good fatigue resistance and creep life, and good fracture toughness are characteristics that make titanium the preferred metal for aerospace applications.
The earliest production application of titanium was in 1952, for the nacelles and firewalls of the Douglas DC-7 airliner. Today, structural components of many aircraft are fabricated of titanium alloys. From the Boeing 757, to the supersonic SR-71 Blackbird, to the F-22 jet fighter, to space satellites and missiles, titanium components play a vital role. Typical applications include titanium fan disks, turbine blades, and vanes in aircraft turbine engines, and cast and forged ...
