This book presents the results of research on the regularities during thermocyclic impact on changes in structural-phase states of functional alloys with low-stability or instability in the area of structural-phase transformations. Without clarification of the physical regularities of the influence of thermomechanical impact on the properties of alloys, it is impossible to develop technological processes of processing functional materials; therefore, the book widely uses the results of many years of research by the authors of the book. It is known that critical temperatures and stresses for martensitic transformation, for example, B 2↔︎ B 19′, in NiTi are very sensitive to cycling. The study of structural-phase states, corresponding to changes in physical-mechanical properties of intermetallics in the area of transformations, is a necessary aspect of understanding the nature of the influence of thermomechanical cycling on the properties of functional alloys. This book is dedicated to the fundamental physical aspects of stability, the influence of structural defects on properties and structural-phase transformations of FCC alloys. This book is useful for a wide range of specialists—scientific researchers and engineers, working in the field of materials science and physics of condensed systems, as well as teachers, postgraduates and students, specializing in the field of materials science.

This book highlights some aspects of processing, microstructure, and properties of materials in fibrous form, or from fibers, with wide applications for textile-oriented and technically oriented advanced products. Emphasis is placed on the physical and chemical nature of the processes, describing the behavior and properties of the investigated materials. The chapters describing the state and expected trends in selected areas summarize not only the published works but also the original results and the critical evaluation and generalization of basic knowledge. In addition to the preparation of materials with new effects, attention is focused on the development of new testing principles, the construction of special devices, and metrological aspects. Research activities cover all types of fibers with a clear shift toward synthetic and specialty fibers for non-clothing applications. This is in line with the current development trend in the field of high-performance fibers, mainly for use as reinforcement in various composite materials and functional fibers for smart textiles. The area of fibrous materials covered in this book is indeed very large. Compressing the basic available information in a reasonable space was therefore a difficult task. The goal in writing this book was to provide a broad area of different results so that the book is suitable for anyone who is generally interested in fibrous materials and their applications for various purposes.

This thesis describes key contributions to the fundamental understanding of materials structure and dynamics from a microscopic perspective. In particular, the thesis reports several advancements in time-domain methodologies using ultrafast pulses from X-ray free-electron lasers (FEL) to probe the interactions between electrons and phonons in photoexcited materials. Using femtosecond time-resolved X-ray diffraction, the author quantifies the coherent atomic motion trajectory upon sudden excitation of carriers in SnSe. This allows the reconstruction of the nonequilibrium lattice structure and identification of a novel lattice instability towards a higher-symmetry structure not found in equilibrium. This is followed by an investigation of the excited-state phonon dispersion in SnSe using time-resolved X-ray diffuse scattering which enables important insight into how photoexcitation alters the strength of specific bonds leading to the novel lattice instability observed in X-ray diffraction. Finally, by combining ultrafast X-ray diffraction and ARPES, the author performs quantitative measurements of electron-phonon coupling in Bi2Te3 and Bi2Se3. The findings highlight the importance of time-resolved X-ray scattering techniques based on FELs, which reveals the details of interplay between electron orbitals, atomic bonds, and structural instabilities. The microscopic information of electron phonon interaction obtained from these methods can rationalize ways to control materials and to design their functional properties.

This book introduces characterizations of hyperordered structures using latest quantum beam technologies, the advanced theoretical methods for understanding the roles of the structures, and the state-of-the-arts materials containing the structures. In this book, the authors focus on the importance of defect complexes to improve functionality of crystals and that of orders of network structures to improve functionality of glass materials. These features can be regarded as interphases between perfect crystals and perfect amorphous, and they are the key factor for the evolution of materials science to a new dimension. The authors call such interphases "hyperordered structures" in this book. This is the first book that comprehensively summarizes glass science, defect science, and quantum beam science. It is valuable not only for active researchers in industry and academia but also graduate students.

This book highlights the latest advances in advanced insulating materials. Energy crisis and environmental pollution are two major themes currently faced by the human society. It is of unprecedented strategic importance to construct a strong smart grid with super/ultra-high voltage network as the backbone and clean energy transmission as the leading force. However, the performance of electrical equipment and devices is greatly determined by the properties of their insulating materials, especially when they have to work in extreme circumstances including high-temperature differences, intense radiation, and strong electric fields. The key advantage of polymers is that their properties could be adjusted by changing their chemical composition and molecular structure. Research on polymer insulating materials has been highly successful as progress has been made in characterizing these properties, designing molecular structures, and studying polymers’ specialized properties. On the other hand, nanodielectrics are prepared by adding certain nanoscale fillers into a polymer matrix to yield better electrical, thermal, and mechanical properties. When the particle pretreatment methods and the content or category of fillers are adjusted, nanodielectrics tend to have greater breakdown strength as well as better high-temperature resistance and space charge suppression. Therefore, this book covers investigations of properties of insulating materials that explore their interface effects and composite structures and introduces findings in methods that improve the performance of electrical devices. The book is not only used as a timely reference for engineering and technical personnel in related fields but also as a comprehensive textbook for college students.

This book deals with the use of the hodograph equation in phase transformations in condensed matter, especially, for crystallization and solidification processes. The main focus of the book is the interpretation of the phase-field equations for isotropic and anisotropic interfaces based on the advanced Gibbs–Thomson and Herring conditions, respectively. Beginning with the basic ideas behind the extended irreversible thermodynamics, the kinetic phase-field model for slow and arbitrarily fast phase transformations is derived where the unified hodograph equation follows from: • the sharp interface limit of the diffuse interface or • the traveling wave solution of the propagating phase field. Under the example of solute trapping and disorder trapping effects, comparing theoretical results with molecular dynamics simulations, and with the analysis of experimental data, the concrete workability of the developed hodograph equation is demonstrated for widest range of driving force in phase transformations.

Overall, it represents a seminal systematic work in the electronic structure theory of the emergent field of nickelate superconductivity.
