Available in PDF, EPUB and Kindle. Book excerpt: Materials science and engineering (MS&E) is by its very nature an inter disciplinary activity. Researchers from a wide variety of disciplines, metal lurgy, ceramics, physics, chemistry, mechanics, electrical and electronic engineering, etc. can and do participate in the MS&E activities. The need and desirability of such an interdisciplinary effort is understandable inas much as advanced or high-performance materials are critical for any of the modern industries. It is almost a given axiom that progress in any field (energy, building materials, transportation, electronics, aerospace, electric power, consumer products, etc.) depends on the availability of suitable In this regard, let me quote from materials having specific characteristics. another work of mine: It is a truism that technological development depends on advances in the field of materials. One does not have to be an expert to realize that a most advanced turbine or aircraft design is of no use if adequate materials to bear the service loads and conditions are not available. Whatever the field may be, the final limitation on advancement depends on materials [1]. It is pertinent to quote from some other sources about a fundamental change that is occurring in the materials field: A fundamental reversal in the relationship between human beings and materials [has occurred]. Its economic consequences are likely to be profound. Historically humans have adapted such natural materials as stone, wood, clay, vegetable fiber and animal tissue to economic uses.

Download or read book Superalloys written by Mahmood Aliofkhazraei and published by BoD – Books on Demand. This book was released on 2015-11-25 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Superalloy, or high-performance alloy, is an alloy that exhibits several key characteristics: excellent mechanical strength, resistance to thermal creep deformation, good surface stability, and resistance to corrosion or oxidation. The crystal structure is typically face-centered cubic austenitic. Superalloy development has relied heavily on both chemical and process innovations. Superalloys develop high temperature strength through solid solution strengthening. An important strengthening mechanism is precipitation strengthening which forms secondary phase precipitates such as gamma prime and carbides. Oxidation or corrosion resistance is provided by elements such as aluminium and chromium. This book collects new developments about superalloys.

Download or read book Alloy Design and Characterization of Strengthened Nickel based Superalloys for Additive Manufacturing written by Jinghao Xu and published by Linköping University Electronic Press. This book was released on 2021-01-28 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nickel-based superalloys, an alloy system bases on nickel as the matrix element with the addition of up to 10 more alloying elements including chromium, aluminum, cobalt, tungsten, molybdenum, titanium, and so on. Through the development and improvement of nickel-based superalloys in the past century, they are well proved to show excellent performance at the elevated service temperature. Owing to the combination of extraordinary high-temperature mechanical properties, such as monotonic and cyclic deformation resistance, fatigue crack propagation resistance; and high-temperature chemical properties, such as corrosion and oxidation resistance, phase stability, nickel-based superalloys are widely used in the critical hot-section components in aerospace and energy generation industries. The success of nickel-based superalloy systems attributes to both the well-tailored microstructures with the assistance of carefully doped alloying elements, and the intently developed manufacturing processes. The microstructure of the modern nickel-based superalloys consists of a two-phase configuration: the intermetallic precipitates (Ni,Co)3(Al,Ti,Ta) known as γ′ phase dispersed into the austenite γ matrix, which is firstly introduced in the 1940s. The recently developed additive manufacturing (AM) techniques, acting as the disruptive manufacturing process, offers a new avenue for producing the nickel-based superalloy components with complicated geometries. However, γ′ strengthened nickel-based superalloys always suffer from the micro-cracking during the AM process, which is barely eliminated by the process optimization. On this basis, the new compositions of γ′ strengthened nickel-based superalloy adapted to the AM process are of great interest and significance. This study sought to design novel γ′ strengthened nickel-based superalloys readily for AM process with limited cracking susceptibility, based on the understanding of the cracking mechanisms. A two-parameter model is developed to predict the additive manufacturability for any given composition of a nickel-based superalloy. One materials index is derived from the comparison of the deformation-resistant capacity between dendritic and interdendritic regions, while another index is derived from the difference of heat resistant capacity of these two spaces. By plotting the additive manufacturability diagram, the superalloys family can be categorized into the easy-to-weld, fairly-weldable, and non-weldable regime with the good agreement of the existed knowledge. To design a novel superalloy, a Cr-Co-Mo-W-Al-Ti-Ta-Nb-Fe-Ni alloy family is proposed containing 921,600 composition recipes in total. Through the examination of additive manufacturability, undesired phase formation propensity, and the precipitation fraction, one composition of superalloy, MAD542, out of the 921,600 candidates is selected. Validation of additive manufacturability of MAD542 is carried out by laser powder bed fusion (LPBF). By optimizing the LPBF process parameters, the crack-free MAD542 part is achieved. In addition, the MAD542 superalloy shows great resistance to the post-processing treatment-induced cracking. During the post-processing treatment, extensive annealing twins are promoted to achieve the recrystallization microstructure, ensuring the rapid reduction of stored energy. After ageing treatment, up to 60-65% volume fraction of γ′ precipitates are developed, indicating the huge potential of γ′ formation. Examined by the high-temperature slow strain rate tensile and constant loading creep testing, the MAD542 superalloy shows superior strength than the LPBF processed and hot isostatic pressed plus heat-treated IN738LC superalloy. While the low ductility of MAD542 is existed, which is expected to be improved by modifying the post-processing treatment scenarios and by the adjusting building direction in the following stages of the Ph.D. research. MAD542 superalloy so far shows both good additive manufacturability and mechanical potentials. Additionally, the results in this study will contribute to a novel paradigm for alloy design and encourage more γ′-strengthened nickel-based superalloys tailored for AM processes in the future.

Download or read book Emerging Engineering Materials written by Mel Schwartz and published by CRC Press. This book was released on 1996-03-21 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the Author's Preface The rapid advances in Materials Science and Engineering . . . have convinced many that the design, production and use of advanced materials will shape future manufacturing industries. Competitive advantage within entire industries is shaped by the quality of the materials available to the manufacturers; the early availability of a new material can be leveraged manyfold. In addition, advanced materials or advanced materials processing can signal the birth or death of entire industries, and access to higher quality and lower cost material has permitted some countries to obtain market dominance in several key industries. Much of the new strategy entails harnessing the potential of innovative technology, that is, going back to the nano and molecular states of materials and new, effective ways to create, process, and eventually use them. Rather than being concerned with a relatively small number of generic materials, each possessing a broad range of uses, the materials sector is increasingly concerned with tailoring a growing list of ever more specialized materials for narrow niche applications. New products with better growth prospects such as high-performance alloys, composites, laminates, and a variety of coatings have been emphasized. Materials firms also have sought ways to overcome the weaknesses of ceramics and fully exploit their formidable strengths. "Functional materials" that do more than support structures have been developed for use in sophisticated electronic, optical, magnetic, and biotech applications. This book will . . . show what materials will be available in the next decade or two, in addition to those currently available and their effect on material design, start-up, and production processes.
