REPORT DATE (DD-MM-YYYY)2 5f. WORK UNIT NUMBER Solid-state processes for creating metal foams are often complex and/or time consuming, and in methods such as gas entrapment, there are practical limits to the porosity achievable due to pore coalescence and percolation. A simple process has been developed to create copper-based metal foam with porosity greater than 65%. The process is unique as expansion occurs within particles, not between them. The method is applied to create a bulk part. The microstructure length scales of the foamed particles are examined using 1-and 2-point microstructure statistics.
