摘要：
A theoretical analysis of the effect of die shape on the stress - strain state during hot extrusion of T-section bar of two different aluminium alloys has been carried out in this study. A finite element method-based program, was used for modelling the extrusion process. Tests were carried out to obtain optimal process parameters of extrusion of T-shaped section, at which no deformation of the section occurs. The effect of the antechamber height and the shape as well as arrangements of the die channel on the geometrical shape of the extruded product have been determined.
