Interface Shear Actions and Mechanical Properties of Nanostructured Dissimilar Al Alloy Laminated Metal Composites

Figure 14

Schematic diagram of the deformation mechanism in LMCs consisting of dissimilar metals [56]: (a) as layer thickness > 50 nm, glide dislocations move on widely spaced planes in soft layer metals and pile up at the interfaces; (b) as layer thickness < 50 nm, dislocations move by bowing within the layers and leave misfit dislocations at the interfaces.
