Abstract
Described herein are methods for forming titanium alloy tubes having an α-β grain structure. The methods include the steps of hot-working a titanium alloy workpiece at a temperature below the β-transus temperature of the workpiece and above the recrystallization temperature of the workpiece to produce an α-β titanium alloy preform hollow. Subsequently, the α-β titanium alloy preform hollow is flowformed, thereby forming a α-β titanium alloy tube.
