ABSTRACT:
A titanium alloy billet having improved response to ultrasonic inspection is described. The billet is given a thermomechanical treatment above the beta transus of the alloy immediately prior to ultrasonic inspection. The treatment may include beta annealing or mechanical deformation above the beta transus. The invention is particularly effective for beta-stabilized alpha-beta and beta titanium alloys.
