| Abstract Scope |
Composite metal foam (CMF) is a novel material consisting of hollow metal spheres embedded in a metallic matrix manufactured using a powder metallurgy technique. CMF displayed excellent mechanical and thermal performances making it ideal in protecting passengers and hazardous cargo. However, joining processes are necessary for large-scale application of CMF. Our prior investigations verified the suitability of induction welding for joining steel CMF up to 2.5 cm thick, leaving room to investigate alternative solid-state joining methods for higher thicknesses. This study applies diffusion bonding to varying thicknesses of steel CMF panels. A combination of tensile testing and scanning electron microscopy of the heat affected zone and fracture surfaces granted insight on the effects of material parameters (e.g., workpiece thickness, panel density, powder specification, and sphere properties) on the applicability of diffusion bonding in joining of Stainless-Steel CMF |
