Titanium alloy - having microstructure of primary alpha in background of acicular/lamellar (alpha and beta)

摘要

Titanium alloy which is prepd. by quenching and annealing to give a microstructure comprising 50-10% primary alpha in a background of acicular or fine lamellar (alpha+beta). These titanium alloys show improved strength and ductility and good resistance to fatigue and crack propagation. They are particularly useful in the mfr. of light strong structures e.g. aeroplane landing gear, aerials etc. helicopter blades, space rockets and other space vehicles.
