Abstract

There are numerous processes for making metallic foams or similar highly porous metallic structures. The various processes can be classified into those starting from metallic melts, those starting from powdered metals, and those using deposition techniques. Most methods work for a specific range of metals and alloys and result in a typical foam structure with closed cells or open, interconnected cells. The most important manufacturing methods and a number of established industrial applications are presented.
