METALLIC FOAMS AND ITS APPLICATION AREAS

Abstract

Engineering materials are generally classified as metals, ceramics, polymers and composite materials. However, today's engineering materials are inadequate in some applications in terms of technical, economic, environmental and aesthetic aspects. The quest to overcome these inadequacies forces researchers to discover new materials with different properties every day. Metallic foams consist of metals or alloys with 75-90% porosity in their structure. Although metallic foams are lighter than other metal materials, they are gaining importance due to their high lightness/strength ratio, ability to absorb impacts and shocks well, high shear and rupture strength, heat and sound insulation, and chemical filtration properties. In this study, existing studies in the literature on metallic foam production methods and production parameters (foaming time, foaming temperature, amount of foaming agent, etc.) were examined and detailed information on the method was given. In addition, comprehensive explanations are given about the application areas of metallic foams in today's industry.
