“…Few data have been reported for the oxidation of nickelbased alloys in steam, so that the information presented here was taken mostly from test loops and laboratory rig tests. 48,86,137,154 Currently, a significant amount of research in this area is in progress, associated with the US Ultra-Supercritical Steam Boiler Tubing programme as well as in European and Japanese programmes, and involves laboratory exposures, boiler-loop tests and component testing. 67,94,[155][156][157] Results of these efforts should be publicly available in the next few years.…”

“…However, others reported that, at 800uC in 41 bar flowing steam, Inconel 600 and 617 exhibited breakaway oxidation kinetics at times .360 h and 1 kh respectively, and that the magnitude of the mass increase following breakaway was much larger for Inconel 600. 76 Pearl et al 154 reported linear rates of metal loss from Inconel 625 oxidised for up to 3?6 kh under heat flux conditions with flowing steam (0?61 m s 21 ) to which additions of 20 ppm O 2 and 2?5 ppm H 2 had been made. The steam pressure was 67 bar and metal temperatures ranged from 566 to 621uC.…”

“…Zabelt [12] reported an oxide thickness of ~20µm for Super 304H exposed to 650°C steam for 1000 hours, while an oxide thickness of ~2µm was observed in the current program. Pearl [13] The EDX results reveal that nearly all of the materials displayed a zone of matrix Cr depletion below chromium-containing oxide layers, as shown in Figure 5. The oxides on nearly all of the austenitic alloys displayed Mn enrichment and contained levels of Ni and Fe that were significantly below matrix concentration levels.…”

The principal objective of this project is to develop materials technology for use in ultrasupercritical (USC) plant boilers capable of operating with 760°C (1400°F), 35 MPa (5000 psi) steam. B. Background and RelevanceIn the 21st century, the world faces the critical challenge of providing abundant, cheap electricity to meet the needs of a growing global population while at the same time preserving environmental values. Most studies of this issue conclude that a robust portfolio of generation technologies and fuels should be developed to assure that the United States will have adequate electricity supplies in a variety of possible future scenarios.The use of coal for electricity generation poses a unique set of challenges. On the one hand, coal is plentiful and available at low cost in much of the world, notably in the U.S., China, and India. Countries with large coal reserves will want to develop them to foster economic growth and energy security. On the other hand, traditional methods of coal combustion emit pollutants and CO2 at high levels relative to other generation options. Maintaining coal as a generation option in the 21st century will require methods for addressing these environmental issues.This project has established a government/industry consortium to undertake a five-year effort to evaluate and develop of advanced materials that allow the use of advanced steam cycles in coal-based power plants. These advanced cycles, with steam temperatures up to 760°C, will increase the efficiency of coal-fired boilers from an average of 35% efficiency (current domestic fleet) to 47% (HHV). This efficiency increase will enable coal-fired power plants to generate electricity at competitive rates (irrespective of fuel costs) while reducing CO2 and other fuel-related emissions by as much as 29%.Success in achieving these objectives will support a number of broader goals. First, from a national prospective, the program will identify advanced materials that will make it possible to maintain a cost-competitive, environmentally acceptable coal-based electric generation option. High sulfur coals will specifically benefit in this respect by having these advanced materials evaluated in high-sulfur coal firing conditions and from the significant reductions in waste generation inherent in the increased operational efficiency. Second, from a national prospective, the results of this program will enable domestic boiler manufacturers to successfully compete in world markets for building high-efficiency coal-fired power plants. -4 -The project is based on an R&D plan developed by the Electric Power Research Institute (EPRI) that supplements the recommendations of several DOE workshops on the subject of advanced materials, and DOE's Vision 21. In view of the variety of skills and expertise required for the successful completion of the proposed work, a consortium that includes EPRI and the major domestic boiler manufacturers (Alstom Power, Babcock and Wilcox (a division of McDermott Technologies Inc.), Foster Wheeler and Babcock...

“…Its original composition was modified to make it weldable and even more creep-resistant [16]. The investigation into understanding the corrosion properties of Inconel 625 in a reactor environment [17] yielded results that indicated a high corrosion resistance up to a temperature of 1500 • F. Inconel 625-clad steel possessed excellent corrosion resistance in severe environments in energy and processing industries [18]. The properties of Inconel have been studied to evaluate its use in the tokamak concept [19] of the nuclear fusion reactor.…”

This study investigates the stability of Inconel–Cu Multimetallic Layered Composites (MMLCs) in nuclear reactor applications using Molecular Dynamics simulations. The focus is on understanding the underlying mechanisms governing the properties of MMLCs for advanced nuclear reactors, specifically, the mechanochemistry of the interface between Inconel and copper alloys. The selection of Inconel–Cu MMLCs is primarily due to copper’s superior thermal conductivity, enhancing heat management within reactors by preventing hotspots and ensuring uniform temperature distribution. This research examines Incoloy 800H and two Inconel variants (718 and 625), assessing their stability at 1000 K after exposure to 10 keV collision cascades up to 0.12 dpa. Notable findings include defect clustering on the {1 2 0} family of planes of Inconel and Cu, with Stacking Faults and Lomer–Cottrell locks on the Inconel side.
