CA 2542078

A high fatigue life superelastic nickel-titanium (nitinol) wire, ribbon, sheet, tubing, or the like is disclosed. The nitinol has a 54.5 to 57.0 weight percent nickel with a balance of titanium composition and has less than 30 percent cold work as a final step after a full anneal and before shape setting heat treatment. Through a rotational beam fatigue test, fatigue life improvement of 37 percent has been observed.

La présente invention se rapporte à un fil, un ruban, une feuille, un tube ou analogues, de nickel-titane (nitinol) superélastiques et présentant une longévité à la fatigue élevée. Le nitinol selon l'invention présente une teneur en nickel comprise entre 54,5 et 57,0 % poids, le reste étant constitué d'une composition de titane, et présente un écrouissage final inférieur à 30 % après un recuit complet et avant un traitement thermique de définition de forme. Un essai de fatigue à faisceau rotationnel a permis de constater une amélioration de la longévité à la fatigue de 37 %.
