Title (EN) Ni-Ti-Al ALLOYS
(FR) ALLIAGES DE Ni-Ti-Al
Abstract:
(EN) Ni-Al-Ti alloys which are plastically deformable at room temperature and have good strength at high temperature comprise a structure of regions of a $g(b) phase of ideal composition NiAl, a $g(b)' phase of ideal composition Ni2TiAl and a $g(g)' phase of ideal composition Ni3Al, the regions being epitaxially related to one another. Preferably the $g(b) phase or the $g(g)' phase is continuous.
(FR) Des alliages de Ni-Al-Ti qui peuvent subir une déformation plastique à température ambiante et présentent une bonne résistance à des températures élevées comprennent une structure de régions composées d'une phase $g(b) de composition idéale NiAl, d'une phase $g(b)' de composition idéale Ni2TiAl et d'une phase $g(g)' de composition idéale Ni3Al, les régions étant en rapport épitaxial les unes avec les autres. De préférence, la phase $g(b) ou la phase $g(g)' est continue.
