Rare Earth Permanent-Magnet Alloys’ High Temperature Phase Transformation by Shuming Pan Pdf

The process of high temperature phase transition of rare earth permanent-magnet alloys is revealed by photographs taken by high voltage TEM. The relationship between the formation of nanocrystal and magnetic properties is discussed in detail, which effects alloys composition and preparation process. The experiment results verified some presumptions, and were valuable for subsequent scientific research and creating new permanent-magnet alloys. The publication is intended for researchers, engineers and managers in the field of material science, metallurgy, and physics. Prof. Shuming Pan is senior engineer of Beijing General Research Institute of Non-ferrous Metal.

Improving the Properties of Permanent Magnets by G.H.M. Koper,M. Terpstra Pdf

The present study complements the study on patents, patent applications and other literature on rare earth metals based permanent magnets by Frits Andriessen and Marten Terpstra, published by Elsevier Applied Science in 1989, and complements in part the book on Nd-Fe permanent magnets edited by LV. Mitchell, which was the result of a workshop organized by the Commission of the European Communities and held in Brussels on 25 October 1984. The difference between the content of the first book and that of the present study is that the first is more specifically directed to various kinds and compositions of alloys used in newly developed magnets, while the present book emphasises the improvements obtained when using particular alloys. The study edited by Mitchell deals more specifically with the economic, physical and chemical aspects of rare earth metals based magnet alloys, their properties compared with the more common and classical magnets such as ferro-cobalt alloy magnets, and their applications to various fields of technology. From the present study it has become apparent that there exist only a few patents and patent applications covering a specific use of particular magnets having specific properties to a circuit, arrangement, device or electric motor. This appears to be due to the fact that every manufacturer of such circuits or arrangements applying magnets naturally wants to employ the most effective magnets.

Nuclear Science Abstracts by Anonim Pdf

NSA is a comprehensive collection of international nuclear science and technology literature for the period 1948 through 1976, pre-dating the prestigious INIS database, which began in 1970. NSA existed as a printed product (Volumes 1-33) initially, created by DOE's predecessor, the U.S. Atomic Energy Commission (AEC). NSA includes citations to scientific and technical reports from the AEC, the U.S. Energy Research and Development Administration and its contractors, plus other agencies and international organizations, universities, and industrial and research organizations. References to books, conference proceedings, papers, patents, dissertations, engineering drawings, and journal articles from worldwide sources are also included. Abstracts and full text are provided if available.

Permanent Magnetic Materials and their Applications by K.H.J. Buschow Pdf

Permanent magnets play an increasingly important role in modern society because they are vital components of numerous domestic and industrial devices. The last few decades have witnessed a quite extraordinary development in the use of hard magnetic materials, especially after the advent of rare earth permanent magnets. The rare earth permanent magnets are unequalled because they combine a high magnetization with an extraordinary magnetic hardness which allows the use of such magnets having the extreme shapes and small dimensions as required in modern devices.

Theory and Application of Rare Earth Materials by Changzhen Wang Pdf

This book starts with a theoretical introduction of the rare earth materials, and it subsequently analyzes the essential characteristics of these materials from elements, compounds to physical chemistry and metal materials, etc. Under the supplementary explanation of experimental data and results, the research is gradually guided into the multi-domain application scene. Through extensive analyses, this book displays comprehensively the distinguished values of the rare earth materials and the theoretical, empirical, and practical significance of rare earth materials is unraveled. It also covers an exhaustive review of 17 rare earth elements, their characteristics, and more possibilities in physical chemistry, functional materials, metallurgy, composites and engineering, and their prospects in production and technical applications. In-depth account of the whole spectrum of rare earth material research makes this book a unique reference to academic researchers, students, and engineers.

Rare Earth Permanent Magnets by A.S. Nowick Pdf

Rare Earth Permanent Magnets presents the discussion of the metallurgy and properties of rare earth permanent magnet alloys. The monograph initially provides the elementary aspects of magnetism to enable the reader sufficient understanding of permanent magnetism. The book then discusses the rare earth elements and their alloys with cobalt, copper, and iron; the magnetic properties of various intermetallic compounds relevant to permanent magnets; a detailed account of cast permanent magnets of the Co-Cu-Sm and Co-Cu-Ce systems and their modifications; the important methods of making and manufacturing rare earth permanent magnets by powder metallurgy methods; and comparisons between the well-known permanent magnets and the new rare earth materials. This text will be of value to students, materials engineers, and scientists.
