Electromagnetic field is an available online method to increase bonding strength of clad sheet manufactured by horizontal twin-roll casting (HTRC).In this paper,an electric current pulse (ECP) and a complex field (static magnetic field (SMF) together with ECP) are exerted during HTRC of steel/aluminum clad sheet.The produced clad sheet has good appearance,and no visible defects exist at the bonding interface.The inter-diffusion zone at Fe/Al interface in ECP and SMF+ECP sheets is 3 and 4 μm,respectively,and the latter increases slightly compared with that in non-field sheet.The average peel strengths (APS) of ECP and SMF+ECP sheet are 14 and 21 N/mm,respectively,which increase by 2 and 9 N/mm compared with 12 N/mm of non-field sheet.The APS increment in SMF+ECP sheet is resulted from the increment of interface bonding spots and the enhancement of inter-diffusion zone width.
