Processing Of High Temperature Superconductors At High Strain

The discovery of high-temperature superconductivity [1986] by Bendnorz and Muller in the La-BA-Cu-O system resulted in very extensive research work about the discovery and synthesis of other high-temperature superconductors, such as Y-BA-Cu-O and Bi-Sr-Ca-Cu-O. These new superconducting materials, possessing superconductivity above liquid nitrogen

Drawing from physics, mechanical engineering, electrical engineering, ceramics, and metallurgy, high-temperature superconductivity (HTSC) spans nearly the entire realm of materials science. This volume presents each of those disciplines at an introductory level, such that readers will ultimately be able to read the literature in the field.

The 39 peer-reviewed papers in this book provide a state-of-the-art update of exciting work currently being carried on in the area of high-temperature superconductors. Topics of discussion include processing for high critical current densities, flux-pinning mechanisms, processing for the development of flux-pinning centers, chemistry, phase relations, stoichiometry, processing/microstructure relationships, and prototype devices for practical applications.

The achievement of large critical currents is critical to the applications of high-temperature superconductors. Recent developments have shown that melt processing is suitable for producing high Jc oxide superconductors. Using magnetic forces between such high Jc oxide superconductors and magnets, a person could be levitated. This book has grown largely out of research works on melt processing of high-temperature superconductors conducted at ISTEC Superconductivity Research Laboratory. The chapters build on melt processing, microstructural characterization, fundamentals of flux pinning, critical current, and applications of bulk monolithic superconductors. The text also describes the basic mechanism of levitation and its application. This book will be useful for research workers, engineers, and graduate students in the field of superconductivity.

In contrast to research on the fundamental mechanisms of High-Temperature Superconductivity, in recent years we have seen enormous developments in the fabrication and application of High-Tc-superconductors. The two volumes of High Temperature Superconductivity provide a survey of the state of the technology and engineering applications of these materials. They comprise extended original research papers and technical review articles written by physicists, chemists, materials scientists and engineers, all of them noted experts in their fields. The interdisciplinary and strictly application-oriented coverage should benefit graduate students and academic researchers in the mentioned areas as well as industrial experts. Volume 1 "Materials" focuses on major technical advancements in High-Tc materials processing for applications. Volume 2 "Engineering Applications" covers numerous application areas where High-Tc superconductors are making tremendous impact.
