Cross-section of the “AMg3/D16/AMg3” composite in the bond zone (a); shear zone from D16 side after shear test (b) Ta b l e 1 Mechanical properties of “AMg3/D16/AMg3” composite after rolling with thickness reduction of 45 % Yield stress, MPa Ultimate strength, MPa Elongation, % Shear bond strength, MPa 279 292 7.2 43 further increase in the rolling reduction ratio on the bond strength, the dependences of the surface extend Y and the maximum pressure in the deformation zone pmax on reduction ratios were studied (fig. 7). It should be noted that at reduction ratio ε equal to 0.55 or more, the surface extend Y is less than reduction ratios ε, which means an increasing inhomogeneity of deformation over the thickness of composites.
