Gamma Prime Coarsening Behavior of Nickel Superalloy Supercast 247A after prolonged Thermal Exposure Second National Conference on Recent Developments in Mechanical Engineering 38 Page M.E.Society's College of Engineering
Ab Nickel based superalloys are commonly used materials in the aero industry and more specifically in the hot section of aero engines. These nickel and nickel iron based superalloys are precipitation strengthened alloys with a face centered cubic gamma matrix.
Abstract Gamma-prime-strengthening of four nickel-based superalloys has been investigated theoretically and experimentally. The critical resolved shear stress (CRSS) of under- and of peak-aged single crystals has been measured as a function of the radius and of the volume fraction f of the gamma-prime-particles, f ranged from 0.07 to 0.47.

Some of the authors previously developed an alloy design program for gamma-prime precipitation hardening nickel-base superalloys [1,2]. By this program, calculations were made possible for gamma/gamma-prime phase equilibrium as well as other structural
(gamma prime) precipitation (MA-6000E). Nickel-base alloys are available in both cast and wrought forms. Highly alloyed compositions, such as Rene 95, Udimet 720, and IN100, are produced by ...
Even though chemical composition of Ni-38Cr-3.8Al is simple, the microstructure is complex because it consists of the gamma/alpha Cr lamellar structure with the fine gamma prime particles. Therefore, in this study, we investigated the influence of Cr concentration on the cellular precipitation behaviour.

A superalloy, or high-performance alloy, is an alloy with the ability to operate at a high fraction of its melting point. Several key characteristics of a superalloy are excellent mechanical strength, resistance to thermal creep deformation, good surface stability, and resistance to corrosion or oxidation. The crystal structure is typically ...
