Abstract

A combination of surface mechanical attrition treatment (SMAT) and co-rolling can produce large-scale laminated nanostructured stainless steel (SS) with both high strength and high ductility. Recent numerical results based on the cohesive finite element method have revealed that brittle nanograined interface layer can enhance the ductility of the co-rolled SMATed SS. Here, numerical investigation focuses on effects of both shape of the bilinear cohesive law and mesh size and shows that the larger thickness of the phases in uniform state allows the use of coarser meshes.
