Abstract

A method of forming an aircraft component includes providing an aluminum alloy. The method further includes mixing a shape memory alloy (SMA) with the aluminum alloy to form a combination of the SMA and the aluminum alloy. The method further includes forming the aircraft component with the combination of the SMA and the aluminum alloy.

First claim

What is claimed is:

1. A method of forming an aircraft component, the method comprising:
mixing a shape memory alloy (SMA) with an aluminum alloy to form a combination of the SMA and the aluminum alloy, wherein mixing the SMA with the aluminum alloy includes:
providing the SMA in a wire form having a length that is less than 0.0197 inches,
retaining the SMA in the wire form in a single location,
melting the aluminum alloy, and
pouring the aluminum alloy over the SMA in the wire form; and

forming the aircraft component with the combination of the SMA and the aluminum alloy, wherein the aluminum alloy is Al—Cu—Mg—Ag—TiB2.

2. The method of claim 1 , wherein the SMA includes a nickel titanium alloy.

3. The method of claim 1 , wherein forming the aircraft component includes forming the aircraft component using at least one of casting, powder metal, forging, extrusion, or additive manufacturing.

4. The method of claim 1 , wherein the combination of the SMA and the aluminum alloy includes between 0.1 percent (0.1%) and 18% of the SMA by volume.

5. The method of claim 1 , wherein the forming the aircraft component is via additive manufacturing.

6. The method of claim 1 , wherein the retaining the SMA in the wire form in a single location includes retaining the SMA in a cast.
