Abstract
A light metallic closed cellular material has been developed. Polymer particles coated with a pure aluminum layer using a physical vapour deposition system were sintered by a spark plasma sintering method and polystyrene foamed particles coated with nickel-phosphorus alloy layer using electro-less plating were pressed into the green pellets and sintered at high temperatures in a vacuum condition. Metallic closed cellular materials that have lightweight were then fabricated. The compressive tests were carried out to measure the mechanical properties of these materials. The results showed that these light metallic closed cellular materials were brittle and do not have long plateau region.
