Les alliages métalliques conventionnels sont constitués d'un élément majoritaire, comme le cuivre, le fer, ou le nickel, associé à d'autres éléments présents en plus faible quantité. En 2004, Cantor et al. réalisent un alliage composé de 5 éléments dont la répartition est équiatomique. Ces alliages à haute entropie (AHEs) suscitent un intérêt croissant pour les applications en conditions extrêmes grâce à leur bon comportement à haute température et leur grande stabilité chimique. Par ailleurs, les alliages à mémoire de forme à haute température (HT-AMFs) sont sujets à une faible durée de vie liée à la précipitation de phase aux joints de grains au-dessus de 200°C. Dans le cadre de cette thèse, des alliages combinant la résistance à haute te...
