Abstract

Nickel-base superalloys that are in service for long periods of time in fossil energy powerplants have microstructures that evolve with time. The strengthening gamma prime phase coarsens, and in some alloys, a new phase (eta) forms at grain boundaries, and its effect on creep performance is not fully understood.

Effects of Eta Phase on Creep Performance of the Nickel-Base Superalloy 263

Conference Mohale, Ninad; Milligan, Walter; Sanders, Paul; ...

In wrought nickel-base alloys used at elevated temperatures for extended periods of time, it is commonly observed that unwanted phases may nucleate and grow. One such phase is the eta phase, based on Ni3Ti, which is a plate-shaped precipitate that nucleates at the grain boundaries and grows at the expense of the strengthening gamma prime phase. In order to study the effects of eta phase on creep performance, Alloy 263 was modified to contain 3 different microstructures: standard (contains gamma prime); aged (contains gamma prime and eta); and modified (contains only eta and no gamma prime). These microstructures were thenmore »« less

Creep-induced microstructural evolution in a nickel-based superalloy designed for advanced ultra-supercritical boilers

Journal Article Xu, Qingshuang; Cao, Tieshan; Ye, Fei; ... - Materials Characterization

Highlights: • Microstructural evolution of a nickel-based superalloy during long-term creep was investigated. • Precipitate-free zones (PFZs) widely arose near the grain boundary under stress. • The coarsened and elongated particles in the PFZs were identified as γ′ precipitates. • The boundary movement plays a role in evolution of grain boundary precipitates. - Abstract: Long-term microstructural stability is a major concern for candidate materials used in advanced ultra-supercritical (A-USC) power plants. In the present work, precipitation behavior of a nickel based superalloy designed for A-USC boilers, with a base composition of Ni-25Cr-20Co, was investigated during long-term thermal exposure under differentmore »« less

Design, Creep Performance and Deformation Behavior of an Eta-Phase Strengthened Nickel-Base Alloy for A-USC Power Plant Applications

Conference Milligan, Walter; Sanders, Paul; White, Calvin; ...

By utilizing computational thermodynamics in a Design of Experiments approach, it was possible to design and manufacture nickel-base superalloys that are strengthened by the eta phase (Ni3Ti), and that contain no gamma prime (Ni3Al,Ti). The compositions are similar to Nimonic 263, and should be cost-effective, and have more stable microstructures. By varying the aging temperature, the precipitates took on either cellular or Widmanstätten morphologies. The Widmanstätten-based microstructure is thermally stable at high temperatures, and was found to have superior ductility, so development efforts were focused on that microstructure. High temperature tensile test and creep test results indicated that the performancemore »« less

Mechanisms of High Temperature/Low Stress Creep of Ni-Based Superalloy Single Crystals

Technical Report Mills, Michael

Cast nickel-based superalloys are used for blades in land-based, energy conversion and powerplant applications, as well as in aircraft gas turbines operating at temperatures up to 1100 C, where creep is one of the life-limiting factors. Creep of superalloy single crystals has been extensively studied over the last several decades. Surprisingly, only recently has work focused specifically on the dislocation mechanisms that govern high temperature and low stress creep. Nevertheless, the perpetual goal of better engine efficiency demands that the creep mechanisms operative in this regime be fully understood in order to develop alloys and microstructures with improved high temperaturemore »« less

Thermo-mechanical fatigue of the monocrystalline nickel-base superalloy CMSX-6

Conference Kraft, S; Mughrabi, H

Total strain-controlled thermo-mechanical fatigue (TMF) tests were performed between 600 and 1,100 C on as-grown near to [001]-orientated specimens of the {gamma}{prime} precipitate-strengthened monocrystalline nickel-base superalloy CMSX-6. The strain-temperature cycle (in-phase, out-of-phase, diamond) has a strong influence on the mechanical and microstructural events occurring during TMF. For given temperature intervals, the fatigue lives were shortest for out-of-phase tests and longest for in-phase tests, respectively. For all cycle shapes applied, the maximum tensile stress level was concluded to be the lifetime-limiting factor. The failure mode of the investigated alloy depends also on the conducted strain-temperature history. While strongly localized crystallographic shearingmore »« less
