Title: (DE) HERSTELLUNG VON ZWEIWEGFORMGEDÄCHTNISTEILEN
(EN) MANUFACTURE OF TWO-WAY SHAPE MEMORY DEVICES
(FR) FABRICATION DE DISPOSITIFS A MEMOIRE DE FORME BIDIRECTIONNEL
Abstract: front page image
(EN) A process is provided for the manufacture of a two-way shape memory alloy and device. The process of the invention allows a reversible adjustment of the characteristic transformation temperatures, as well as the direction of the two-way shape memory effect, at the final stage of manufacture.
(FR) L'invention concerne un procédé de fabrication d'un alliage et d'un dispositif à mémoire de forme dans les deux sens. Le procédé de l'invention permet un réglage réversible des températures de transformation caractéristiques, de même que l'effet de mémoire de forme dans les deux sens, lors de l'étape finale de fabrication.
