|Abstract:||An understanding of the work hardening behaviour of particle reinforced metal matrix composites is crucial in optimising the parameters for deformation processing of these materials. The microstructure and mechanical properties of these composites can be altered by a suitable aging treatment. In particular, aging can be used to maximise the strength or the ductility of the composite. The strength is maximised in the peak aged condition while the as solutionised condition hau relatively higher 1 ductility. In this paper a modified continuum model is used to relate the work hardening behaviour of the composite to microstructural parameters. The model is also used to predict the fracture strain of the composite for the two aging conditions and is quite accurate for both aging conditions. © 1997 The Institute of Materials.|
