• This article describes a theoretical model of the generalized kinematic velocity field for the axisymmetrical flow of a bi-component (metal-quasi-liquid lubricant) system that can be applied to dies with either straight or curved profiles. The differentiation of the derived analytical dependencies of the velocity of any point within the deformation zone enables the determination of the deformation strains. It is shown that the proposed model describes quite accurately the form - and is satisfactory in respect of the dimensions - of the plastic zone in the hot hydro-extrusion of hardening alloy AlCu4Mg1.
