Restoration models for hot working of metals and alloys are reviewed in the context of their applicability to friction stir welding (FSW) and friction stir processing (FSP). Two of these models are used to interpret microstructure and microtexture data for two aluminum alloys subjected to FSP. The need for further experiments and model extensions to accommodate the transients and steep gradients in the strain, strain rate and temperature experienced by materials during FSW and FSP are discussed.
