Microstructural Evolution and Tensile Properties of a Corrosion-Resistant Ni-Based Superalloys Used for Industrial Gas Turbines
نویسندگان
چکیده
As an important mechanical property, tensile behavior has been regarded as indicator for the creep and thermal fatigue properties of Ni-based superalloys. The property superalloys is closely related to amount, size, distribution γ'-phase carbides. To further clarify deformation mechanism CM247LC alloy, this study investigated its solidification characteristics directionally-solidified heat-treated microstructure. dependence on varied temperature ranging between 650 950 ℃ discussed in detail. It was found that at dominated by shearing dislocations into γ'-precipitates form superlattice stacking faults. At 800 ℃, K-W lock leads anomalous yield effects. bypassing γ'-precipiates. results provide a comprehensive understanding alloy are beneficial development corrosion-resistant

Hot Corrosion in Gas Turbines
DURING COMBUSTION in the gas turbine, sulfur from the fuel reacts with sodium chloride from ingested air at elevated temperatures to form sodium sulfate. The sodium sulfate then deposits on the hot-section components, such as nozzle guide vanes and rotor blades, resulting in accelerated oxidation (or sulfidation) attack. This is commonly referred to as “hot corrosion.” Sulfur in the fuel is gen...
متن کاملMicrostructural aspects of fatigue in Ni-base superalloys.
Nickel-base superalloys are primarily used as components in jet engines and land-based turbines. While compositionally complex, they are microstructurally simple, consisting of small (50-1000 nm diameter), ordered, coherent Ni(3)(Al,Ti)-type L1(2) or Ni(3)Nb-type DO(22) precipitates (called γ(') and γ(''), respectively) embedded in an FCC substitutional solid solution consisting primarily of Ni...
متن کاملMODELLING THE MATERIAL PROPERTIES AND BEHAVIOUR OF Ni-BASED SUPERALLOYS
At the last two Superalloy meetings at Seven Springs, work on the development of thermodynamic modelling tools for application to multi-component Ni-based superalloys has been presented. Such modelling has become quite widespread, providing significant benefit. However, its applicability often falls short from directly providing the information that is actually required and, by itself, cannot b...
متن کاملOnline Fault Detection and Isolation Method Based on Belief Rule Base for Industrial Gas Turbines
Real time and accurate fault detection has attracted an increasing attention with a growing demand for higher operational efficiency and safety of industrial gas turbines as complex engineering systems. Current methods based on condition monitoring data have drawbacks in using both expert knowledge and quantitative information for detecting faults. On account of this reason, this paper proposes...
متن کاملModel Based Diagnosis and Supervision of Industrial Gas Turbines
Supervision of performance in gas turbine applications is important in order to achieve: (i) reliable operations, (ii) low heat stress in components, (iii) low fuel consumption, and (iv) efficient overhaul and maintenance. To obtain good diagnosis performance it is important to have tests which are based on models with high accuracy. A main contribution of the thesis is a systematic design proc...
