Abstract

On fabrique par extrusion un tube en métal à mémoire à base de NiTi, ce qui consiste à: a) commencer à partir d'une ébauche de métal à mémoire; b) pratiquer un perçage central dans ladite ébauche; c) introduire un noyau dans le perçage central, l'ébauche étant encastrée dans une enveloppe et entourée également, de préférence, par deux pignons, ce qui l'isole de l'atmosphère ambiante; d) chauffer et extruder l'ébauche encastrée; e) supprimer les extrémités de l'ébauche extrudée; f) supprimer également le noyau et l'enveloppe. Ceci permet de fabriquer des tubes en métal à mémoire à base de NiTi d'une longueur inégalée jusqu'à présent, telle que >= 1/2 m.
