The early stage mechanisms of grain refinement during ECAE of a single-phase aluminium alloy have been studied using the EBSD technique. It was found that, in addition to the formation of shear-plane cell bands and shear bands by ‘‘simple shear’’, the development of deformation bands due to orientation splitting contributed significantly to the refinement of microstructure. ‘‘Regular’’ slab-like deformation bands and ‘‘irregular’’ transitional bands were observed after the first pass; both… CONTINUE READING
