Download or read book Frontiers in Magnetic Materials written by Chen Wu and published by CRC Press. This book was released on 2022-08-12 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book aims to provide comprehensive and practical guidance on magnetism and magnetic materials. It involves four parts, focusing on fundamental magnetism, hard magnetic materials, soft magnetic materials and other functional magnetic materials. Part I highlights the ubiquity of magnetism and the close relationships between magnetic materials and our daily life. Perspectives on magnetism from Engineering and Physics are provided to introduce the two unit systems, followed by the origin and categories of magnetisms. An introduction of important parameters during magnetization and magnetic measurement techniques are then provided to lay a solid foundation for the readers for better understandings of the design and development of different magnetic materials. Important magnetic materials are then introduced in the subsequent parts, delivering an overview of design principles, production technologies, research developments and real-world applications. For instance, rare-earth-free and rare-earth-based hard magnetic materials as well as soft magnetic materials such as Fe-based alloys, composites and ferrites are discussed. Other functional magnetic materials span a wide range, involving smart materials with magneto-X effects, together with magnetic materials for applications including electromagnetic wave absorption, biomedicine and catalysis, etc. For these magnetic materials, more emphasis is placed on the latest advances and interdisciplinary perspectives.

Book excerpt: Alloying: Understanding the Basics is a comprehensive guide to the influence of alloy additions on mechanical properties, physical properties, corrosion and chemical behavior, and processing and manufacturing characteristics. The coverage considers "alloying" to include any addition of an element or compound that interacts with a base metal to influence properties. Thus, the book addresses the beneficial effects of major alloy additions, inoculants, dopants, grain refiners, and other elements that have been deliberately added to improve performance, as well the detrimental effects of minor elements or residual (tramp) elements included in charge materials or that result from improper melting or refining techniques. The content is presented in a concise, user-friendly format. Numerous figures and tables are provided. The coverage has been weighted to provided the most detailed information on the most industrially important materials.

Download or read book Rare Earth Materials written by A.R. Jha and published by CRC Press. This book was released on 2014-06-17 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent studies indicate that China accounts for about 96 percent of the world’s supply of rare earth materials (REMs). With REMs becoming increasingly important for a growing number of high-tech applications, appropriate action must be taken to mitigate the effects of a shortage of critical REMs in defense systems and components. Bringing together information previously available only from disparate journal articles and databases, Rare Earth Materials: Properties and Applications describes the unique characteristics and applications of 17 REMs. It defines their chemical, electrical, thermal, and optical characteristics. Maintaining a focus on physical and chemical properties, it addresses the history and critical issues pertaining to mining and processing of REMs. In this book, Dr. A.R. Jha continues his distinguished track record of distilling complex theoretical physical concepts into an understandable technical framework that can be extended to practical applications across commercial and industrial frameworks. He summarizes the chemical, optical, electrical, thermal, magnetic, and spectroscopic properties of REMs best suited for next-generation commercial and military systems or equipment. Coverage includes extraction, recycling, refinement, visual inspection, identification of spectroscopic parameters, quality control, element separation based on specific application, pricing control, and environmental / geo-political considerations. Potential applications are identified with an emphasis on scientific instruments, nuclear resonance imaging equipment, MRI systems, magnetic couplers for uranium enrichment equipment, battery-electrodes, electric motors, electric generators, underwater sensors, and commercial and military sensors. The book describes unique applications of rare earth magnets in all-electric and hybrid electric cars and microwave components. It also considers the use of rare earth magnets in commercial and military systems where weight and size are the critical design requirements. Suitable for both students and design engineers involved in the development of high-technology components or systems, the book concludes by summarizing future applications in electro-optic systems and components, including infrared lasers, diode-pumped solid-state lasers operating at room temperatures, and other sophisticated military and commercial test equipment
Download or read book Supermagnets Hard Magnetic Materials written by G.J Long and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 840 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book you are now holding represents the final step in a long process for the editors and organizers of the Advanced Study Institute on hard magnetic materials. The editors interest in hard magnetic materials began in 1985 with an attempt to better understand the moments associated with the different iron sites in Nd Fe B. These 14 moments can be obtained from neutron diffraction studies, but we qUickly realized that iron-57 Mossbauer spectroscopy should lead to a better determination of these moments. However, it was also realized that the complex Mossbauer spectra obtained for these hard magnetic materials could not be easily understood without a broad knowledge of their various structural, electronic, and magnetic properties. Hence it seemed useful to the editors to bring together scientists and engineers to discuss, in a tutorial setting, the various properties of these and future hard magnetic materials. We believe the inclusion of engineers as well as scientists in these discussions was essential because the design of new magnetic materials depends very much upon the mode in which they are used in practical devices.
