Abstract

Alliage monocristallin de nickel ayant de nombreuses propriétés de fonderie et d'usage des superalliages monocristallins à base de nickel de plus haute masse volumique et se pretant à la coulée d'ailettes et pales pour turboréacteurs à haute performance. La masse volumique plus faible de l'alliage le rend utile pour la reconstruction de turboréacteurs de conception relativement ancienne qui ne résistent pas aux efforts centrifuges exercés par les anciens superalliages monocristallins à haute masse volumique.
