Abstract (en)
A nickel-based superalloy comprising in wt% Co=1-8%, W=7-15%, Mo=1-8%, Ta=7-15%, Al=4-9%, having a mechanical strength at very high temperature, up to 1300°C, higher than that of the known superalloys by raising the T solidus of the alloy and developing an intermetallic ³ phase in high percentages by volume, higher than 70%, which maintains its properties practically unchanged until the incipient melting of the alloy, having a T solvus , i.e. a solvus temperature of the ³ phase higher than the T solidus of the alloy, i.e. the temperature at which the liquid phase starts being present.
