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.

Disclosed is a carbon nanoparticle-porous skeleton composite material, its composite with lithium metal, and their preparation methods and use. In the carbon nanoparticle-porous skeleton composite material, the porous skeleton is a carbon-based porous microsphere material with a diameter of 1 to 100 m or a porous metal material having internal pores with a micrometer-scale pore size distribution, and the carbon nanoparticles are distributed in the pores and on the surface of the carbon-based porous microsphere material or the porous metal material. The carbon nanoparticle-porous skeleton composite material is mixed with a molten lithium metal to form a lithium-carbon nanoparticle-porous skeleton composite material. The carbon nanoparticles present in the material can better conduct lithium ions during the battery cycle, thereby inhibiting the formation of lithium dendrites, and improving the safety and cycle stability of the battery.

A castable, moldable, or extrudable structure using a metallic base metal or base metal alloy. One or more insoluble additives are added to the metallic base metal or base metal alloy so that the grain boundaries of the castable, moldable, or extrudable structure includes a composition and morphology to achieve a specific galvanic corrosion rates partially or throughout the structure or along the grain boundaries of the structure. The insoluble additives can be used to enhance the mechanical properties of the structure, such as ductility and/or tensile strength. The insoluble particles generally have a submicron particle size. The final structure can be enhanced by heat treatment, as well as deformation processing such as extrusion, forging, or rolling, to further improve the strength of the final structure as compared to the non-enhanced structure.

A composite material is provided having functionalized carbon nanotubes and a metal matrix. It is obtained by a process including dispersing functionalized carbon nanotubes or a mixture of functionalized carbon nanotubes and of at least one metal, in an open-pore or semi-open-pore metal foam, in order to form a composite structure, and compacting the composite structure obtained in the preceding stage in order to form the composite material in the form of a solid mass.
