WebThere are many procedures that can be utilized to produce metal foams such as bubbling gas through molten metal, stirring of foaming agent in molten metal, consolidation of metal powder, vapor phase of electrodeposition, sintering of hollow spheres, dissolution of gas in liquid metal etc ( Ashby et al., 2000 ). WebAbstract. A foam is commonly defined as a dispersion of gas bubbles in a liquid. In a “solid foam” the liquid has changed into a gel or a solid phase after making the dispersion. The volume fraction φ of gas in a foam is mostly between 0.5 and 0.97; if φ > about 0.75, the bubbles necessarily deform one another.
