nickel based superalloy

  • Superalloy - Wikipedia

    Nickel-based superalloys are used in load-bearing structures to the highest homologous temperature of any common alloy system (Tm = 0.9, or 90% of their melting point). Among the most demanding applications for a structural material are those in the hot sections of turbine engines.

  • Iron-Based Superalloys | Machine Design

    Iron-Based Superalloys. Iron, nickel, and cobalt-based alloys used primarily for high-temperature applications are known as superalloys. The iron-based grades, which are less expensive than cobalt or nickel-based grades, are of three types: alloys that can be strengthened by a .

  • Nickel-Based Superalloys: Part One :: Total Materia Article

    A superalloy, or a high-performance alloy, is an alloy that exhibits excellent mechanical strength and creep resistance at high temperatures, good surface stability, and corrosion and oxidation resistance.A superalloy's base alloying element is usually nickel, cobalt, or nickel-iron. Superalloy development has relied heavily on both chemical and process innovations and has been driven ...

  • Nickel-based superalloys - Thermo-Calc Software

    The nickel–aluminium system is the binary basis for Ni-based superalloy compositions. As the amount of aluminium added is large enough, an ordered L12 phase (γ') forms from the FCC matrix (γ) with the nominal composition of Ni3Al. Today's superalloys can also be based on cobalt or nickel-iron.

    Dynamic recrystallization of polycrystalline γ–γ' nickel‐based superalloys has been extensively studied in terms of mechanisms and kinetics. As in many materials with low stacking fault energy, under forging conditions, the main softening mechanism is discontinuous dynamic recrystallization.


    In general, the oxidation resistance of the Whereas the early nickel-base superalloys con-nickel- and cobalt-base alloys is considered to be tained 16-20 per cent chromiurn, the later ones relatively good. The oxides formed are tightly contain 10-15 per cent, a portion of the chromium adherent and protective.
