Mechanical Properties and Bonding Mechanism of the Mg/Al Clad Sheet Manufactured by the Corrugated Roll

In this research, corrugated Mg/Al clad sheet with good interface bonding was prepared a rolling mill of upper roll and lower flat under the conditions 35% reduction 400 °C. The mechanical properties were studied using transverse tensile test, Vickers microhardness as well its bending properties. Moreover, mechanism researched through three-dimensional contour analysis. results showed that UTS at trough position highest (~296 MPa), peak lowest (~257 MPa). maximum fracture EL ~13.4%, while minimum ~10.6%. process, cracked first due to uneven stress distribution in matrixes. Then, Mg broke, finally failed final fracturing Al sheet. metal four positions higher than Mg, which closely related dislocation strengthening could be divided into stages: extrusion deformation, rubbing fracture, compound extension completion.
