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 tubular preform and a second material composition of at least one of a secondary 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 of titanium. 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 manufacturing a landing gear component, comprising:
- mixing a plurality of powdered metals comprising titanium, iron, vanadium, and aluminum to produce a powder blend;
- cold isostatic pressing the powder blend;
- sintering the cold pressed powder blend to form a billet;
- performing a spraycasting operation with the billet to produce a rough tubular preform, wherein the spraycasting operation includes melting the sintered billet to form a molten metal and spraycasting the molten metal over a cylindrical mandrel to produce the rough tubular preform;
- performing thermomechanical processing operations on the rough tubular preform to generate a near net shape tubular preform, wherein the thermomechanical processing operations comprise hot radial forging and wherein the thermomechanical processing operations further include at least one of solutionizing heat treatment or aging;
- performing material removal operations on the near net shape tubular preform including removal of a mandrel to generate a tubular preform;
- loading the tubular preform into an additive manufacturing machine;
- forming, via friction stirred additive manufacturing, a secondary structural element integral with the tubular preform to form a part, wherein the secondary structural element is at least one of a rounded rectangular lug portion, a chamfered rectangular lug portion, or a lobed portion;
- heat treating the part to generate a functionally graded monolithic structure;
- and
- machining the part to form the landing gear component.
