Systems and methods for wire deposited additive manufacturing using titanium

Abstract

A metallic part is disclosed. The part may comprise a functionally graded monolithic structure characterized by a variation between a first material composition of a first structural element and a second material composition of at least one of a second structural element. The first material composition may comprise an alpha-beta titanium alloy. The second material composition may comprise a beta titanium alloy.

What is claimed is: 
     
         1 . An article of manufacture including a metallic component comprising:
 a functionally graded monolithic structure characterized by a variation between a first material composition of a first structural element and a second material composition of a second structural element, wherein   each of the first material composition and the second material composition comprises at least one of a titanium metal or an alloy,   wherein the second structural element is formed of a wire feedstock,   wherein the wire feedstock comprises a heat treated wire drawn from a sintered billet of powdered metals, and   the sintered billet of powdered metals comprise titanium hydride, iron, vanadium, and aluminum.   
     
     
         2 . The article of manufacture of  claim 1  wherein, wherein the first material composition comprises a substantially iron free titanium alloy. 
     
     
         3 . The article of manufacture  claim 2 , wherein the second material composition comprises a titanium alloy with an iron composition 3% by weight or more. 
     
     
         4 . The article of manufacture of  claim 3 , wherein the sintered billet of powdered metals comprise between 4% and 6% by weight iron, between 0.5% to 2% by weight aluminum, and between 6% to 9% by weight vanadium. 
     
     
         5 . The article of manufacture of  claim 3 , wherein the heat treated wire comprises between 0.25% and 0.50% by weight oxygen and between 0.001% and 0.015% by weight hydrogen. 
     
     
         6 . The article of manufacture of  claim 5 , wherein the heat treated wire is heat treated by at least one of annealing, solutionizing, or aging. 
     
     
         7 . The article of manufacture of  claim 6 , wherein the heat treated wire has undergone at least one of a beta phase transformation, a beta anneal, or an alpha beta anneal during the at least one of annealing, solutionizing, or aging.
