Available in PDF, EPUB and Kindle. Book excerpt: The need for alternate energy sources has led to the develop ment of prototype fusion and MHD reactors. Both possible energy systems in current designs usually require the use of magnetic fields for plasma confinement and concentration. For the creation and maintenance of large 5 to 15 tesla magnetic fields, supercon ducting magnets appear more economical. But the high magnetic fields create large forces, and the complexities of the conceptual reactors create severe space restrictions. The combination of re quirements, plus the desire to keep construction costs at a mini mum, has created a need for stronger structural alloys for service at liquid helium temperature (4 K). The complexity of the required structures requires that these alloys be weldable. Furthermore, since the plasma is influenced by magnetic fields and since magnet ic forces from the use of ferromagnetic materials in many configur ations may be additive, the best structural alloy for most applica tions should be nonmagnetic. These requirements have led to consideration of higher strength austenitic steels. Strength increases at low temperatures are achieved by the addition of nitrogen. The stability of the austenitic structure is retained by adding manganese instead of nickel, which is more expensive. Research to develop these higher strength austenitic steels is in process, primarily in Japan and the United States.

Download or read book Austenitic Stainless Steels written by Wojciech Borek and published by BoD – Books on Demand. This book was released on 2017-12-20 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stainless steel is still one of the fastest growing materials. Today, the austenitic stainless steel with the classic composition of 18% Cr and 8% Ni (grade 304L) is still the most widely used by far in the world. The unique characteristic of stainless steel arises from three main factors. The versatility results from high corrosion resistance, excellent low- and high-temperature properties, high toughness, formability, and weldability. The long life of stainless steels has been proven in service in a wide range of environments, together with low maintenance costs compared to other highly alloyed metallic materials. The retained value of stainless steel results from the high intrinsic value and easy recycling. Stainless steel, especially of austenitic microstructure, plays a crucial role in achieving sustainable development nowadays, so it is also important for further generations.

Available in PDF, EPUB and Kindle. Book excerpt: The compositional redistribution in the direction of depth in austenitic Fe-Ni-Cr-Si-C alloys under 200-keV proton irradiation was examined experimentally using the cross-section technique. After the solution-annealed Fe-25.5Ni-14.7Cr-0.97Si-0.026C and Fe-25.7Ni-14.5Cr-2.85Si-0.026C alloys were irradiated at 873 K by 200-keV protons to the dose of 175 dpa at the peak-damage position for the different irradiation times of 0.1 and 1.37 Ms, the depth profile of composition was measured with an energy dispersive X-ray microanalyzer. Significant depletion of nickel and enrichment of chromium were observed in the peak-damage region ranging from about 0.85 to 1.05 ?m in depth, similarly in both the short-time (0.1 Ms) and long-time (1.37 Ms) irradiations. Slight enrichment of iron and slight depletion of silicon were also observed in the peak-damage region. The observed compositional changes in the peak-damage region is in good qualitative agreement with theoretical prediction, although some quantitative discrepancies between them remain.

Download or read book High Temperature Corrosion and Materials Applications written by George Y. Lai and published by ASM International. This book was released on 2007-01-01 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: George Lai's 1990 book, High-Temperature Corrosion of Engineering Alloys, is recognized as authoritative and is frequently consulted and often cited by those in the industry. His new book, almost double in size with seven more chapters, addresses the new concerns, new technologies, and new materials available for those engaged in high-temperature applications. As we strive for energy efficiency, the realm of high-temperature environments is expanding and the need for information on high temperature materials applications was never greater. In addition to extensive expansion on most of the content of the original book, new topics include erosion and erosion-corrosion, low NOx combustion in coal-fired boilers, fluidized bed combustion, and the special demands of waste-to-energy boilers, waste incinerators, and black liquor recovery boilers in the pulp and paper industry. The corrosion induced by liquid metals is discussed and protection options are presented.

Download or read book Surface Hardening of Austenitic Fe Cr Ni Alloys for Accident tolerant Nuclear Fuel Cladding written by Zhen Li and published by . This book was released on 2018 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three Fe–Cr–Ni alloys (AISI-316L, AL-6XN and IN-718) were surface-engineered by infusion of interstitial solutes (C and N) for potential application as nuclear fuel cladding. However, an ’activation’ process, which removes the Cr-rich oxide layer that blocks the infusion of interstitial solutes, is needed before these alloys can be successfully surface-engineered. An innovative and highly effective aqueous acid activation process was applied. The surfaces of these Fe–Cr–Ni alloys are successfully activated in 300 s to 600 s at room temperature compared to 21.6 ks at carburizing temperature with gaseous HCl activation. Moreover, the activated surface of Fe–Cr–Ni alloys can be well protected by immersing in ethanol before these specimens are transfered into the carburizing furnace. Specimens of the Fe–Cr–Ni alloy AISI-316L, IN-718 and AL6-XN were successfully surface-engineered by low-temperature carburization and low-temperature nitro-carburization. Near the alloy surface, up to 15 at% to 20 at% of carbon and 20 at% of nitrogen were observed in Fe–Cr–Ni alloys – without detectable carbides. This high carbon and nitrogen fraction results in a threefold increase of surface hardness, significantly improved wear resistance and corrosion resistance of Fe–Cr–Ni alloys. Cr depletion can be seen in all the surface-engineered Fe–Cr–Ni alloys. Low-temperature carburization and low-temperature nitro-carburization can induce ferromagnetism in the surface of IN-718 ni-based alloy. The ferromagnetism detected in low-temperature carburized and low-temperature nitro-carburized IN-718 may have interesting applications, independent of nuclear technology. Thermal stability of low-temperature carburized material was tested by post-carburization heat exposure. No observable difference of properties (i. e. no observable precipitates, no detectable diffusion of interstitial solutes and no obvious change of the shapes of X-ray diffraction peaks and Auger concentration profiles) appeared in surface-engineered Fe–Cr–Ni alloys after exposure at 620K in air in comparison with as-carburized Fe–Cr–Ni alloys. However, properties of low-temperature carburized and low-temperature nitro-carburized Fe–Cr–Ni alloys showed significant variation (i. e. metallography, X-ray diffractometry and scanning Auger microprobe profile) after exposure in the simulated loss of coolant accident environment (1070K for 3.6 ks) compared to those of as-carburized Fe–Cr–Ni alloys. Carbon depletion and infusion were observed in the low-temperature carburized and low-temperature nitro-carburized Fe–Cr–Ni alloys after exposure to 1070K for 3.6 ks. Among all these surface-engineered Fe–Cr–Ni alloys, low-temperature carburized IN-718 did not show observable oxidation after exposure to the simulated loss of coolant accident environment. Non-treated and low-temperature carburized AISI-316L have severe stress corrosion cracking on the surface after exposure in a boiling water reactor simulated environment. However, stress corrosion cracking is not observable in the carburized IN-718 specimen. Finally, exposure to 1.5MeV proton irradiation at elevated temperature (620K), as well as exposure in the simulated loss of coolant accident environment (with no radiation at 1070K for 3.6 ks), causes precipitation of nano-sized Cr-rich carbides in low-temperature carburized IN-718. These prevented the loss of Cr (as well as C) by evaporation under the loss of coolant accident. Among all the surface-engineered alloys, low-temperature carburized IN-718 has the most potential for nuclear cladding.
