Download or read book High Temperature Corrosion in Molten Salts written by César A.C. Sequeira and published by Trans Tech Publications Ltd. This book was released on 2003-06-10 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerous commercial processes operate at temperatures exceeding 500 degrees Celsius. The materials used in high-temperature structures have design constraints which are in addition to those on materials used at, or near to, room temperature. These important additional constraints include time-dependent inelastic strain (creep), thermal stability of the microstructure and high-temperature corrosion. The addition of these constraints to those of low cost, strength, toughness, machinability, formability, weldability, and combinations of these, has led to the intensive development, over the past 50 years, of an extensive group of metallic materials: generally referred to as "high-temperature alloys".

Download or read book Chromium and Chromium Alloys written by D. J. Maykuth and published by . This book was released on 1966 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various alloying additions have been discovered which render unalloyed chromium much less susceptible to low-temperature embrittlement as well as to nitridation in air at elevated temperatures. These include additions of the Group IIIA metals, magnesia, and carbides based on the Groups IVA and VA metals. Of these additions, only the carbides contribute significantly to the hot strengthening of chromium. The combination of selected carbides and solid-solution-strengthening elements such as tungsten, molybdenum, and/or tantalum, has resulted in experimental alloys which retain useful strengths at temperatures through 1316 C (2400 F). These high strengths are achieved at some sacrifice in the low-temperature ductility of chromium. Also, despite the improvements afforded in the oxidation and nitridation resistance of chromium through alloying, no alloys are available which are capable of service in long-time exposures in air above 982 C (1800 F) without suffering some property degradation.

Download or read book Nuclear Corrosion Science and Engineering written by Damien Feron and published by Elsevier. This book was released on 2012-02-21 with total page 1073 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corrosion of nuclear materials, i.e. the interaction between these materials and their environments, is a major issue for plant safety as well as for operation and economic competitiveness. Understanding these corrosion mechanisms, the systems and materials they affect, and the methods to accurately measure their incidence is of critical importance to the nuclear industry. Combining assessment techniques and analytical models into this understanding allows operators to predict the service life of corrosion-affected nuclear plant materials, and to apply the most appropriate maintenance and mitigation options to ensure safe long term operation. This book critically reviews the fundamental corrosion mechanisms that affect nuclear power plants and facilities. Initial sections introduce the complex field of nuclear corrosion science, with detailed chapters on the different types of both aqueous and non aqueous corrosion mechanisms and the nuclear materials susceptible to attack from them. This is complemented by reviews of monitoring and control methodologies, as well as modelling and lifetime prediction approaches. Given that corrosion is an applied science, the final sections review corrosion issues across the range of current and next-generation nuclear reactors, and across such nuclear applications as fuel reprocessing facilities, radioactive waste storage and geological disposal systems. With its distinguished editor and international team of expert contributors, Nuclear corrosion science and engineering is an invaluable reference for nuclear metallurgists, materials scientists and engineers, as well as nuclear facility operators, regulators and consultants, and researchers and academics in this field. Comprehensively reviews the fundamental corrosion mechanisms that affect nuclear power plants and facilities Chapters assess different types of both aqueous and non aqueous corrosion mechanisms and the nuclear materials susceptible to attack from them Considers monitoring and control methodologies, as well as modelling and lifetime prediction approaches
Download or read book High temperature Corrosion Study of Alloys in Molten MgCl2 KCl Eutectic Salt written by Yuxiang Peng and published by . This book was released on 2019 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: The MgCl2-KCl molten salt has been proposed as one of the heat transfer fluids (HTFs) in the solar energy system because of its potential thermal properties. This research investigates the corrosion behavior and protection strategies of Haynes 230 (H230), Incoloy 800H (800H), and Stainless Steel 316 (SS316) in MgCl2-KCl molten salt at high temperature. First of all, the corrosion rates of different alloys are determined by performing the long-term static corrosion experiments. The morphologies of the surface and corrosion depths are examined by scanning electron microscopy (SEM) equipped with an energy dispersive X-ray spectrometer (EDS). Secondly, the effect of Ni on the corrosion behavior of the alloys is studied in this research. When the alloy is connected with Ni, the corrosion rate is higher than that without connection in the same condition. Thirdly, the electrochemical tests of three alloys are also investigated in present research work. Tafel curves are plotted to calculate the corrosion potentials and corrosion rates of three alloys at different temperatures. Fourthly, two methods are proposed and studied to protect the alloys from severe corrosion in the MgCl2-KCl molten salt: 1) adding a sacrificial anode into the salt, and 2) coating a high-corrosion-resistance alloy. Mn, Zn, and Zr are chosen as the sacrificial anode materials to protect the alloys from further corrosion. The result showed that additions of inhibitor into the molten salts decrease the corrosion rates of the tested alloy. Pure Ni, Al2O3, Ni-Al alloy, and Cr-Fe-Al alloy are chosen to coat the tested alloy. Long-term corrosion experiments, as well as electrochemical tests of alloys with and without different coatings, are studied in present work. The results demonstrated that all these coatings decreased the corrosion rates of the tested alloys. Finally, the diffusion models are constructed to predict the distribution of the Cr in the different alloys after corrosion. And the results are comparable to the experimental data. In conclusion, H230 showed the highest corrosion resistance in the MgCl2-KCl salt proved by long-term corrosion test and electrochemical tests. Different inhibitors and coatings all improved the corrosion resistance of alloys in the molten salt.
