Lattice severe deformation rolling (LSDR) principle has obvious advantages in solving technical problems such as low bonding strength, warping and severe edge cracking in Mg/Al laminate rolling process, however, the formation mechanism and characteristics of corrugated bonding interface are still understudied. Therefore, the severe non-uniform deformation effect of corrugated roll on the laminate rolled under LSDR principle was analyzed by finite element numerical simulation, and the formation characteristics of corrugated bonding interface and the distribution laws of strain along the interface were explained, which were verified by rolling experiment. The results show that when the Mg/Al laminate is rolled by the LSDR principle, the component plate, especially the Mg alloy plate, undergoes two periodic deformations along the rolling direction (RD) and the transverse direction (TD), which promotes the formation of corrugated structure in the bonding interface along two directions, and the corrugated period is slightly larger along RD and is slightly smaller along TD. The difference in the formation characteristics and morphologies of corrugated bonding interface along RD and TD leads to the difference in the distributions and mechanical properties of intermetallic compound layer along two directions. Thus, the research content provides the experimental reference for the in-depth exploration of LSDR principle and the preparation of high-performance Mg/Al laminates.
