Alpha-Beta Titanium Alloy Tubes And Methods Of Flowforming The Same

US Patent:
2006007, Apr 6, 2006
Filed:
Dec 3, 2004
Appl. No.:
11/004629
Inventors:
Matthew Fonte - Charlestown MA, US
John Heymans - Salem NH, US
George Durfee - Grafton MA, US

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.
