Deformation of metals at increasing strain leads to a microstructural evolution which follows a continuous refinement down to the nanometre dimension. The increasing structural refinement generally leads to an increase in strength and a decrease in ductility. However these trends are reversed when the deformed microstructure is coarsened for example during a heat treatment. Optimisation of mechanical properties therefore relies on characterization and modelling of process structure-property relationships.
