A detailed structural characterisation is the basis for an analysis of the structure-flow stress relationship in deformed metals. This is demonstrated for aluminium (99 % purity) deformed to very large strain by cold rolling. The analysis is repeated for aluminium of similar purity deformed to large strains by accumulative roll bonding (ARB), which introduces a significantly different microstructure than that observed after cold rolling. The structure-flow stress relationship of ARB materials is discussed and related to that observed for cold rolled samples. (C) 2004 Published by Elsevier B.V.
