  • Alpha-beta titanium alloy tubes and methods of flowforming the same
    Publication number: 20060070688
    Abstract: Described herein are methods for forming titanium alloy tubes having an ?-? grain structure. The methods include the steps of hot-working a titanium alloy workpiece at a temperature below the ?-transus temperature of the workpiece and above the recrystallization temperature of the workpiece to produce an ?-? titanium alloy preform hollow. Subsequently, the ?-? titanium alloy preform hollow is flowformed, thereby forming a ?-? titanium alloy tube.
