Treatise on Materials Science and Technology, Volume 14: Metallurgy of Superconducting Materials covers the practical use of metallurgy of superconducting materials. The book discusses the phenomenon of superconductivity; the theory of superconductors; the applications of superconductivity and the demands these applications make on materials' properties and requirements. The text also describes the metallurgy of niobium-titanium alloy conductors; the physical metallurgy of A15 compounds; and the electron microscopy of superconducting materials. The metallurgy of conductors made from A15 material, the properties required, as well as the development of superconductors for ac power transmission are considered. The book further tackles the metallurgy of niobium surfaces, and the effects of radiation on superconductors. Metallurgists, physicists, materials scientists, materials engineers, and graduate students studying superconductors will find the book invaluable.
