Stress-strain curves have been obtained for a superplastically deformed industrial 60/40 brass tested in tension under constant true strain-rate conditions at 600‡C. This alloy produced by extrusion shows a fibrous structure with elongated grains. It is shown that the flow stress is influenced by two microstructural factors, i.e. the change of phase shape which becomes approximately equiaxed and the variation of the phase size during superplastic deformation. These factors are of different relative importance according to the strain-rate.
