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.
