Abstract

Procédé de production de matériaux ou articles polycristallins à grains fins, selon lequel le matériau est comprimé, sous l'effet d'une force de pression exercée par un outil de compression et d'une déformation par cisaillement, à travers une matrice (10) dans laquelle ledit matériau est dévié, ce matériau prenant une direction de compression qui s'écarte de la direction de la force de pression exercée par l'outil de compression. On obtient ainsi plusieurs changements de direction du matériau à l'intérieur de la matrice. La présente invention concerne également une matrice (10) pour une filière de boudineuse pourvue d'un canal de compression qui dévie le matériau à plusieurs reprises pendant l'extrusion.
