Abstract Scope |
Multi-material lightweight materials have recently attracted considerable attention in the automotive industry, in particular where a trade-off between reduced weight and improved performances is required. Nevertheless, joining of dissimilar lightweight magnesium (Mg) and aluminum (Al) alloys is challenging due to the marked differences in their metallurgical and physical properties and the formation of brittle intermetallic compound layers: an Al3Mg2 layer on the Al alloy side and a Mg17Al12 layer on the Mg alloy side. In this study, the feasibility of improving adhesive bonding of an explosive-welded AZX611 (Mg-6Al-1Zn-1Ca-0.3Mn in wt.%)/A6N01 (Al-0.7Mg-0.5Si-0.3Cu in wt.%) joint was explored by conventional hot-rolling process. 7 mm thick plates were rolled to 1 mm thick sheets with different rolling temperatures and thickness reduction per pass to provide an in-depth understanding of the relationship between the rolling condition, adhesive bonding and interface microstructure of the AZX611/A6N01 joint sheet. |
