摘要

Composite metal foamComposite Metal Foam (CMF) is a novelSolid-state bonding 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, joiningJoining processes are necessary for large-scale application of CMF. Our prior investigations verified the suitability of induction welding for joiningJoining steel CMF up to 2.5 cm thick, leaving room to investigate alternative solid-state joiningJoining methods for higher thicknesses. This study applies diffusionDiffusion bonding to varying thicknesses of steel CMF panels. A combination of tensile testing and scanning electron microscopyScanning electron microscopy of the heat-affected zone and fracture surfaces granted insight on the effects of material parameters (e.g., workpiece thickness, panel densityDensity, powder specification, and sphere properties) on the applicability of diffusionDiffusion bonding in joiningJoining of stainless steel CMF.
