Method and apparatus for the extrusion of tubing, sheets and profile shapes, wherein shearing strains in the material being extruded through a die (2) serve to orient the mi- crostructure of the material so that its strength properties are improved in the direction (15) transverse to the extruding direction (9).
Un procédé et un appareil permettent d'extruder des tubes, des plaques et des profilés. Les contraintes de cisaillement, imposées au matériau extrudé à travers une filière (2), servent à orienter la microstructure de ce matériau de façon à en améliorer les caractéristiques de résistance dans le sens (15) transversal au sens (9) d'extrusion.
