Presentation Title Hybrid Pore Formation in Microporous Cu Spheres

Abstract Scope Using unique processing, we create millimeter-sized copper spheres with micron and sub-micron pores by a combination of entrapped argon and the reduction of oxide particles. This allows multi-stage foaming to be applied such that either mostly closed or open porosity can be created through choice of annealing environment. These spheres are formed through planetary ball milling of Cu and CuO, which results in a refined microstructure that is partially stabilized at elevated temperature by CuO particles and the existence of small pores before annealing. During annealing, the individual spheres, or components made from them, become highly porous throughout and able to achieve hierarchical porosity. This system serves as a template for other hybrid foaming strategies and lends particular insight into the microstructural development of these materials as well as their bulk mechanical properties. The importance of the chemistry-structure-process-property relationships will be emphasized.
