Brief description The thermal stability of nanocrystalline alloys produced by severe plastic straining. An exciting class of materials has emerged with grain sizes two orders of magnitude finer than that produced by conventional processing. These nanocrystalline alloys are produced by intense plastic straining termed equal channel angular extrusion (ECAE). The aim of the project is to incorporate novel experimental techniques, using single crystals, in situ annealing and 3-D computer simulation to develop a fundamental understanding of microstructural stability during ECAE and subsequent thermal treatment. Such advances in our understanding of boundary mobility in fine-scale microstructures is important for evaluating their stability and, hence, the possible commercial exploitation of these materials.
