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.
Claims13
A method of additive manufacturing, comprising:
- mixing a plurality of powdered metals comprising titanium, iron, vanadium, and aluminum to produce a powder blend;
- cold isostatic pressing and sintering the powder blend to form a billet;
- performing a wire forming operation on the billet to produce a worked wire, wherein the wire forming operation includes extruding the billet through a die;
- heat treating the worked wire to produce a heat treated wire;
- coiling the heat treated wire onto a feed spool;
- loading a first structural element into an additive manufacturing machine, the first structural element having a first side, a second side, a first face, and a second face;
- loading the feed spool into the additive manufacturing machine;
- printing a second structural element of the heat treated wire from the feed spool, the second structural element being integral to the first structural element to form a part, wherein the second structural element is deposited over including depositing a first flange portion proximate the first side and extending perpendicular from the first face in a first direction;
- and
- heat treating the part to generate a functionally graded monolithic structure.
