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.

Claims

exact text as granted — not AI-modified
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; and   forming the aircraft component with the combination of the SMA and the aluminum alloy.   
     
     
         2 . The method of  claim 1 , wherein the aluminum alloy includes aluminum (Al), copper (Cu), magnesium (Mg), silver (Ag), titanium (Ti), and boron (B). 
     
     
         3 . The method of  claim 2 , wherein the aluminum alloy is Al—Cu—Mg—Ag—TiB2. 
     
     
         4 . The method of  claim 2 , wherein the SMA includes a nickel titanium alloy. 
     
     
         5 . 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. 
     
     
         6 . The method of  claim 1 , wherein mixing the SMA with the aluminum alloy includes at least one of mixing particles of the SMA in powder form with particles of the aluminum alloy in powder form or mixing the SMA in the powder form with liquid aluminum alloy. 
     
     
         7 . The method of  claim 1 , wherein mixing the SMA with the aluminum alloy includes:
 providing the SMA in 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.   
     
     
         8 . The method of  claim 1 , wherein mixing the SMA with the aluminum alloy includes:
 melting the aluminum alloy; and   mixing the SMA with the aluminum alloy during the melting of the aluminum alloy.   
     
     
         9 . 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. 
     
     
         10 . A method of forming an aircraft component, the method comprising:
 mixing a shape memory alloy (SMA) an aluminum alloy including aluminum (Al), copper (Cu), magnesium (Mg), silver (Ag), titanium (Ti), and boron (B); to form a combination of the SMA and the aluminum alloy, the SMA including a nickel titanium alloy; and   forming the aircraft component with the combination of the SMA and the aluminum alloy.   
     
     
         11 . The method of  claim 10 , wherein mixing the SMA with the aluminum alloy includes at least one of mixing particles of the SMA in powder form with particles of the aluminum alloy in powder form or mixing the SMA in the powder form with liquid aluminum alloy. 
     
     
         12 . The method of  claim 10 , wherein mixing the SMA with the aluminum alloy includes:
 retaining the SMA in a wire form in a single location, the SMA in the wire form having a length that is less than 0.0197 inches;   melting the aluminum alloy; and   pouring the aluminum alloy over the SMA in the wire form.   
     
     
         13 . The method of  claim 10 , wherein the combination of the SMA and the aluminum alloy includes between 0.1 percent (0.1%) and 18% of the SMA by volume. 
     
     
         14 . An aircraft component, comprising:
 an aluminum alloy; and   a shape memory alloy (SMA) mixed together with the aluminum alloy to form a combination of the SMA and the aluminum alloy.   
     
     
         15 . The aircraft component of  claim 14 , wherein the aluminum alloy includes aluminum (Al), copper (Cu), magnesium (Mg), silver (Ag), titanium (Ti), and boron (B). 
     
     
         16 . The aircraft component of  claim 15 , wherein the aluminum alloy is Al—Cu—Mg—Ag—TiB2. 
     
     
         17 . The aircraft component of  claim 15 , wherein the SMA includes a nickel titanium alloy. 
     
     
         18 . The aircraft component of  claim 14 , wherein the SMA is provided in powder form and the aluminum alloy is provided in powder form, and the SMA and the aluminum alloy are combined while both in the powder form. 
     
     
         19 . The aircraft component of  claim 14 , wherein the SMA is provided in wire form having a length that is less than 0.0197 inches and the aluminum alloy is combined with the SMA while the aluminum alloy is melted. 
     
     
         20 . The aircraft component of  claim 14 , wherein the combination of the SMA and the aluminum alloy includes between 0.1 percent (0.1%) and 18% of the SMA by volume.
