Deformation Characteristic and Microstructure Evolution of Mg/Al Clad Plate in Corrugated Rolling

doi:10.3901/JME.2025.08.085

Abstract

Abstract: In order to solve the problems of low bonding strength and serious shape warpage of composite plates prepared by traditional flat roll rolling process, Mg/Al clad plates were prepared by corrugated+flat rolling and the mechanical properties were tested. The tensile strength of the Mg/Al composite plate obtained by corrugated+flat rolling is 324.50MPa, which is 11.8% higher than the traditional flat rolling; the shear strength is 82.55MPa, which is 8.0% higher than the traditional flat rolling. A three-dimensional thermal-mechanical coupled finite element model for corrugated rolling of Mg/Al clad plates was established, and the changes in stress, strain, and temperature during the rolling process were analyzed. During the corrugated rolling process, the direction of shear stress on the surface of the Mg plate changes multiple times, leading to the alternating presence of multiple forward slip zones and backward slip zones within the deformation zone, and the formation of multiple cross shear zones. This shearing action generated additional deformation heat, increased the temperature of the Mg plate, and coordinated the deformation of dissimilar metals. By integrating the characteristics of metal temperature and strain distribution obtained from finite element model, the microstructure evolution at characteristic positions in the corrugated rolling deformation zone was analyzed through rolling block experiments, and the bonding mechanism of Mg/Al clad plate prepared by corrugated rolling was revealed.
