摘 要：Steel sheet/aluminum foam/steel sheet sandwich structure have higher stiffness than aluminum sheet/aluminum foam/aluminum sheet sandwich.So in this study the aim is to manufacture steel/Al-foam core/steel sandwich panels by rolling of two steel-face sheet and Al-Si powders.The deformation of the rolled-piece,powder grains and the joining deformation of the composite interface are discussed and analyzed in this paper.SEM and EDS of the compound interface are investigated.It was concluded that a metallurgy bonding interface was formed by diffusion reaction and a brittle compound generated.
