摘要
The three-layer clad materials consisting of Al(AA1100) / Mg(AZ31) / Al(AA1100) plate was fabricated by the hot roll bonding method. The crucial technological parameters of manufacturing clad sheet, including the threshold rolling reduction and clad-rolling bonding conditions were investigated. This clad sheet was produced successfully by hot roll bonding with the intermetallic phase formation, which can be observed using conventional optical microscope. The bond interfacial structures of the AZ31 / AA1100 clad material were observed by SEM. It was be researched that the effect of anneal technology on the thickness of diffusion layer and bonding properties of clad plate. The optimal anneal time is presented based on the micro-analysis for the Mg-Al clad plate. The vital procedures of ensuring the qualities and improving the bonding strength of clad plates were described.
