The bulk properties of materials are dictated by how it is processed and the resulting microstructure. This relationship, that dominates mechanical behavior, is even more pronounced at the small length-scales found in ultrafine grained (UFG) and nanoscale hierarchical materials. An effective way to create superior materials is to engineer procedures that control these microstructures. Ultra-fine layered composites are a prime candidate in the study of these relationships because they have superior mechanical properties and can be produced in bulk through accumulative roll bonding, a severe plastic deformation (SPD) technique. The incorporation of Mg as a major constituent of the laminate, while challenging, may result in superior structural materials due to its low density and high specific-strength. Here, we discuss the challenges of fabricating Mg-based UFG layered composites and a computational model that can predict the development of their properties and internal structures as a function of how it is processed.
