Title (EN) PROCESS FOR THE IMPROVED DUCTILITY OF NITINOL
(FR) PROCEDE AMELIORANT LA DUCTILITE DU NITINOL
Abstract: front page image
(EN)A process for treating nitinol so that desired mechanical properties are achieved. In one embodiment, the process comprises the steps of exposing the nitinol to a primary annealing temperature within the range of approximately 475 °C to 525 °C for a first time period, and thereafter exposing the nitinol to a secondary annealing temperature within the range of approximately 550 °C to 800 °C for a second time period. The invention also includes nitinol articles made by the process of the invention.
(FR)L'invention concerne un procédé de traitement du nitinol permettant d'obtenir des propriétés mécaniques voulues. Dans un mode de réalisation, le procédé comporte les étapes consistant à exposer le nitinol à une température de recuit primaire se situant approximativement entre 475 °C et 525 °C pendant une première période, et exposer ensuite le nitinol à une température de recuit secondaire se situant approximativement entre 550 °C et 800 °C pendant une deuxième période. L'invention concerne également des articles en nitinol fabriqués selon le procédé de l'invention.
