Abstract

Les propriétés des AMF sont dues à une transformation de phase solide solide réversible induite par la contrainte ou la température. Pour les AMF de type Ni49,75%at-Ti, c’est une transformation isochore qui, d’une phase cubique (austénite), forme une phase monoclinique (martensite) avec 24 orientations possibles (variantes). A partir des géométries locales et des énergies par variante, nous proposons un modèle polycristallin multiaxial qui rend compte du fort couplage thermomécanique lors de la transformation de phase. Des essais quasi statiques permettent de le valider.
