摘要：
Superalloy with a nickel base matrix having good mechanical properties whenot in respect of tensile strength, creep resistance, low cycle fatigue and resistance to crack-propagation of which the composition in percentages by weight is as follows: Cr 11 to 13; Co 8 to 17; Mo 6 to 8; Nb less than or equal to 1.5; Ti 4 to 5; Al 4 to 5; Hf less than or equal to 1; C, B, Zr each less than or equal to 500 ppm; Ni remainder to 100. The alloy can be manufactured advantageously by powder metallurgy techniques and used in the manufacture of turbo machine disks.
