Abstract Scope Formation of high angle grain boundaries is believed to be the primary mechanism governing the strain-induced grain refinement in metals. With an increasing plastic strain, usually a steady-state microstructure with submicro-sized randomly-oriented grains is resulted as the mechanically-induced GB migration is activated. Recently surface mechanical grinding treatment (SMGT) was developed to induce high-rate shear deformation with very large strain gradient, with which nanolaminated (NL) structures with low angle grain boundaries (LAGBs) were fabricated in a number of metals. The boundary space ranges from a few nm to a few tens nm, about one order of magnitude smaller than the saturation structural sizes processed by conventional severe plastic deformation. In this talk, the structure characteristics and formation mechanisms of the NL structures will be presented. The effects of strain rates, strain gradients, and processing temperature on the extraordinary structural refinement will be discussed in several samples including pure metals and alloys.
