Most research aimed at modelling microstructural evolution during the thermomechanical processing of metals treats each deformation as a single event which can be described by effective values of strain and strain rate. As modelling techniques become more precise, the detailed nature of the deformation becomes more important. Previous work on modelling hot flat rolling of metals has shown that using equivalent strain to describe static recrystallisation is not sufficiently accurate. For instance, the reversal in shear strain experienced by the metal passing through the roll gap must be taken into account. Flat rolling, while of major economic significance, is not the most complicated type of metal deformation. Section rolling, extrusion and particularly forging involve complicated strain paths for the deformation. At the moment, the significance of the strain path for the flow stress and microstructural evolution of the metal is not known. This project aims to quantify the significance.
