Abstract

La présente invention concerne un alliage Cu-Zn-Al(6%), ainsi qu'un procédé amélioré permettant de réduire la température de transformation martensitique de cet alliage par un traitement de re-mémorisation à basse température de 110 °C à 30 °C, soit une réduction de 80 °C. Selon l'invention, le matériau auparavant mémorisé à haute température est soumis à une re-mémorisation à une température inférieure de sorte que ledit matériau soit utilisé de façon appropriée.
