title = "Extrusion of metal matrix composites-modelling and experiments",
abstract = "An integrated approach has been adopted for the analysis of the extrusion of metal matrix composites. The deformation of composites of the aluminium alloy 6061 and particulate alumina was studied by compression testing over a range of strain rates and temperatures representative of extrusion conditions. The data were fitted to a hyperbolic sine constitutive relation, as is commonly used in the modelling of hot working. The constitutive equations so developed were used in a finite element model to compute the strain rate, strain and temperature distribution in the material during extrusion. Model predictions for the extrusion of round sections are presented together with corresponding plant trial data. The use of the model for the development of extrusion limit diagrams which define optimum operating conditions and product quality is discussed.",
