Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung feinkörniger, polykristalliner Werkstoffen oder Werkstücke, bei dem der Werkstoff unter Aufbringung einer Presskraft durch ein Presswerkzeug und unter Scherverformung durch eine Matrize (10) gedrückt und dabei umgelenkt wird, wobei der Werkstoff eine Pressrichtung einnimmt, die von der Richtung der durch das Presswerk ausgeübten Presskraft abweicht. Dabei wird eine mehrfache Umlenkung des Werkstoffes innerhalb der Matrize durchgeführt. Die Erfindung betrifft ebenfalls eine Matrize (10) für ein Strangpresswerkzeug mit einem den Werkstoff während des Durchdrückens mehrfach umlenkenden Presskanal.
