Metallic foams are advanced lightweight materials with numerous applications in industries such as aerospace, automotive, and construction. Melt processing is a widely employed technique for the production of metallic foams, wherein foaming agents play a crucial role in controlling the foam formation process. This comprehensive review provides an in-depth analysis of foaming agents used in melt processing for lightweight metallic foam production. Various types of foaming agents, including blowing agents, and foam stabilizers are discussed, along with their mechanisms of action and effects on foam microstructure and pore size. The review covers a range of metallic foam systems, with a focus on aluminium and magnesium foams. Furthermore, optimization strategies for foaming agent selection, concentration, and processing parameters are explored, along with recent advances and future research directions in the field. Overall, this review serves as a valuable resource for researchers, engineers, and practitioners interested in the development and application of lightweight metallic foams produced via melt processing techniques.
