Available in PDF, EPUB and Kindle. Book excerpt: Manganese-aluminum alloys with 68-73% Mn were developed for permanent magnet material. Best magnetic properties were obtained in 71% Mn alloys. Maximum energy product was 4.0 x 10 to the 6th power GOe, reached by homogenization, controlled quenching, reducing area 86% by swaging in jackets, and annealing. Process parameters were studied to fine the optima for the brittle alloy. Deformation of the alloy produces a preferred magnetic axis and raises coercive force. Swaging was best, but deforming by turning cast bars into chips on a lathe gave the best ''particle'' magnets and was easiest. A review of the crystal and magnetic structures leads to the deduction that dislocation lines involve Mn atoms arranged antiferromagnetically which subdivide larger ferromagnetic regions. The magnetic saturation is not reached in practical magnetizing field. The magnetic induction decreases with increasing temperatures to Curie point.

Book excerpt: REACT Project: Dartmouth is developing specialized alloys with magnetic properties superior to the rare earths used in today's best magnets. EVs and renewable power generators typically use rare earths to turn the axles in their electric motors due to the magnetic strength of these minerals. However, rare earths are difficult and expensive to refine. Dartmouth will swap rare earths for a manganese-aluminum alloy that could demonstrate better performance and cost significantly less. The ultimate goal of this project is to develop an easily scalable process that enables the widespread use of low-cost and abundant materials for the magnets used in EVs and renewable power generators.

Available in PDF, EPUB and Kindle. Book excerpt: Annotation New edition of a reference that presents the values of properties typical for the most common alloy processing conditions, thus providing a starting point in the search for a suitable material that will allow, with proper use, all the necessary design limitations to be met (strength, toughness, corrosion resistance and electronic properties, etc.) The data is arranged alphabetically and contains information on the manufacturer, the properties of the alloy, and in some cases its use. The volume includes 32 tables that present such information as densities, chemical elements and symbols, physical constants, conversion factors, specification requirements, and compositions of various alloys and metals. Also contains a section on manufacturer listings with contact information. Edited by Frick, a professional engineering consultant. Annotation c. Book News, Inc., Portland, OR (booknews.com).
Download or read book Handbook of Magnetic Hybrid Nanoalloys and their Nanocomposites written by Sabu Thomas and published by Springer Nature. This book was released on 2022-10-27 with total page 1278 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive reference work satisfies the need for in-depth and multidisciplinary coverage of the current state of the art of magnetic hybrid nanoalloys (MHNAs) and their polymer and ceramic nanocomposites. MHNAs represent one of the most challenging research areas in modern science and technology. These materials are stiff and strong with remarkable electronic, mechanical, electrical, thermal and biocompatible properties, and a high potential for multifunctional applications ranging from industry to medicine. The peer-reviewed literature is already extensive, witnessing rapid progress in experimental and theoretical studies on fundamental properties as well as various advanced applications. Part 1 covers theory, modelling, and synthesis (growth and alloying mechanisms) of MHNAs. Formation mechanisms of magneto-electric multiferroic materials, magnetic carbon nanotube (CNTs), and perovskite materials, which are a novel class of next-generation multifunctional nanomaterials, are discussed. The second part focuses on characterization techniques for electrical and dielectrical, rheological, biocompatibility, and other properties, as well as applications in the industrial, agricultural, environmental, and biomedical sectors. Finally, life cycle assessment is considered as essential to the development of nanomaterials and nanoproducts from MHNAs. Advanced undergraduate and graduate students, researchers, and other professionals in the fields of materials science and engineering, polymer science, surface science, bioengineering, and chemical engineering will find comprehensive and authoritative information for solving fundamental and applied problems in the characterization and use of these multifunctional nanomaterials.
Download or read book Handbook of Modern Ferromagnetic Materials written by Alex Goldman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 656 pages. Available in PDF, EPUB and Kindle. Book excerpt: Below is a copy of Professor Takeshi Takei's original preface that he wrote for my first book, Modem Ferrite Teclmology. I was proud to receive this preface and include it here with pride and affection. We were saddened to learn of his death at 92 on March 12, 1992. Preface It is now some 50 years since ferrites debuted as an important new category of magnetic materials. They were prized for a range of properties that had no equivalents in existing metal magnetic materials, and it was not long before full-fledged research and development efforts were underway. Today, ferrites are employed in a truly wide range of applications, and the efforts of the many men and women working in the field are yielding many highly intriguing results. New, high-performance products are appearing one after another, and it would seem we have only scratched the surface of the hidden possibilities of these fascinating materials. Dr. Alex Goldman is well qualified to talk about the state of the art in ferrites. For many years Dr. Goldman has been heavily involved in the field as director of the research and development division of Spang & Co. and other enterprises. This book, Modem Ferrite Technology, based in part on his own experiences, presents a valuable overview of the field. It is testimony to his commitment and bountiful knowledge about one oftoday's most intriguing areas of technology.
