Systems and methods for high strength titanium rod additive manufacturing
A method of titanium rod additive manufacturing may comprise: mixing a plurality of powdered metals comprising titanium, iron, vanadium, and aluminum to produce a powder blend; isostatic pressing the powder blend to form a billet having a cross-sectional profile; cutting the billet to form a rod feedstock having the first cross-sectional profile; loading the rod feedstock into an additive manufacturing machine configured to deposit the rod feedstock; and producing a metallic component from the rod feedstock.
1. A method of titanium rod additive manufacturing, comprising:
mixing a plurality of powdered metals comprising titanium, iron, vanadium, and aluminum to produce a powder blend;
isostatic pressing the powder blend to form a billet having a cross-sectional profile;
cutting the billet to form a rod feedstock having the first cross-sectional profile;
loading the rod feedstock into an additive manufacturing machine configured to deposit the rod feedstock; and
producing a metallic component from the rod feedstock.
2. The method of claim 1 , wherein the titanium is a titanium hydride powder.
3. The method of claim 2 , wherein the powder blend comprises between 4% and 6% by weight iron, between 0.5% and 2% by weight aluminum, and between 6% and 9% by weight vanadium.
4. The method of claim 3 , further comprising sintering the powder blend after the isostatic pressing, wherein the sintering is performed between 900° F. (482° C.) and 1600° F. (871° C.) and under a vacuum.
5. The method of claim 1 , wherein the isostatic pressing is performed within a temperature range between 1652° F. (900° C.) and 2,282° F. (1,250° C.).
6. The method of claim 1 , wherein the additive manufacturing machine comprises a rotating tool having an aperture disposed therethrough.
7. The method of claim 6 , wherein the rod feedstock is fed through the aperture of the rotating tool.
8. The method of claim 1 , wherein a first density of the rod feedstock is less than 100% of a second density for a known specification of a wrought metal alloy associated with a material composition of the powder blend.
9. The method of claim 1 , wherein the cross-sectional profile of the rod feedstock is a substantially square shape.
10. The method of claim 9 , wherein each side length of the rod feedstock is between 0.25 inches (0.635 cm) and 0.5 inches (1.27 cm).
11. The method of claim 10 , wherein loading the rod feedstock further comprises applying an axial force to the rod feedstock to translate the rod feedstock through an aperture of a rotating tool.
