Abstract: A method of fabricating a metal cellular structure includes providing a sol-gel that is a colloid dispersed in a solvent, the colloid including metal-containing regions bound together by polymeric ligands, removing the solvent from the gel using supercritical drying to produce a dry gel of the metal-containing regions bound together by the polymeric ligands, and thermally converting the dry gel to a cellular structure with a coating in at least one step using phase separation of at least two insoluble elements. Also disclosed is a metal cellular structure including interconnected metal ligaments having a cellular structure and a carbon-containing coating around the metal ligaments.

Abstract: A nanocellular single crystal nickel based material is provided having a thermal diffusivity in the range of 0.0002 cm{circumflex over ( )}2/s to 0.02 cm{circumflex over ( )}2/s and a thermal conductivity in the range of 0.024 W/mK to 9.4 W/mK. The nanocellular single crystal nickel based material may be used to form turbine engine components. The nanocellular single crystal nickel based material may be produced by providing a first solution containing a nickel precursor and deionized water, providing a second solution containing a structure controlling polymer/surfactant and an alcohol, mixing the first and second solutions into a solution containing a reducing agent to form a third solution, and processing the third solution to create the nanocellular single crystal based material.

Abstract: A method for fabricating a metal foam component from an aerogel containing a polymer and nanoparticles is disclosed. The method may comprise: 1) exposing the aerogel to a reducing condition at an elevated temperature for a reaction time to provide a metal foam; and 2) using the metal foam to fabricate the metal foam component. At least one of the elevated temperature and the reaction time may be selected so that at least some ligaments of the metal foam have a desired ligament diameter or at least some pores of the metal foam have a desired pore size. The desired ligament diameter may be less than about one micron and the component may be a component of a gas turbine engine.
