Abstract

Le modèle proposé s'inscrit dans le cadre d'une étude sur le comportement micromécanique métallurgique d'un alliage à mémoire de forme (AMF) Cu-Zn-Al durant la transformation martensitique et l'évolution microstructurale.Le modèle montre que la localisation de la déformation plastique après des sollicitations cycliques entraîne des modifications dans les propriétés mécaniques et thermiques. L'originalité du modèle permet de coupler entre les deux transformations de structures en montrant les mécanismes de déformation nécessaires lors des transformations.
