Nonstoichiometry, Disorder and Order in SolidState
This book provides a deep insight into the phenomena of nonstoichiometry, disorder and order in solid state. Nonstoichiometry induced by structural vacancies is widely spread in solid-phase compounds and creates prerequisites for disordered or ordered distribution of atoms and vacancies. Ordering and disordering are possible in any substitutional systems including strongly non-stoichiometric compounds (transition metal carbides, nitrides, oxides and related ternary interstitial compounds), metallic alloys and substitutional solid solutions considered in this book. The monograph contains 11 chapters, which describe the state of the art in the research of order-disorder structural phase transitions in non-stoichiometric compounds and furnish extensive experimental data on the structure and properties of disordered and ordered phases of non-stoichiometric compounds and the correlation between long- and short-range order in ordered alloys, solid solutions and non-stoichiometric compounds. The results of symmetry analysis of disorder-order transformations are considered in detail. Fundamental methods of phase equilibria calculations in non-stoichiometric systems are described and the results of equilibrium phase diagram calculations for ordering systems are presented in this book. The effects of ordering on different properties of strongly non-stoichiometric compounds are exhaustively analyzed and explained. The monograph is intended for specialists in the theory of phase transitions in solids, solid state physics and chemistry and theoretical materials science. Figures 205. Tables 101. References 1039.
