Advances in materials science have given rise to novel materials with unique properties, through the manipulation of structure at the atomic level. Elucidating the shape and form of matter at this scale requires the application of mathematical concepts. This 2006 book presents the geometrical ideas that are being developed and integrated into materials science to provide descriptors and enable visualisation of the atomic arrangements in three-dimensional space. Emphasis is placed on the intuitive understanding of geometrical principles, presented through numerous illustrations. Mathematical complexity is kept to a minimum and only a superficial knowledge of vectors and matrices is required, making this an accessible introduction to the area. With a comprehensive reference list, this book will appeal to those working in crystallography, solid state and materials science.

High-Entropy Alloys, Second Edition provides a complete review of the current state of the field of high entropy alloys (HEA). Building upon the first edition, this fully updated release includes new theoretical understandings of these materials, highlighting recent developments on modeling and new classes of HEAs, such as Eutectic HEAs and Dual phase HEAs. Due to their unique properties, high entropy alloys have attracted considerable attention from both academics and technologists. This book presents the fundamental knowledge, the spectrum of various alloy systems and their characteristics, key focus areas, and the future scope of the field in terms of research and technological applications.

This book provides a complete review of the current state of the art in the field of high entropy alloys (HEA). The conventional approach to alloy design is to select one principal element and add elements to it in minor quantities in order to improve the properties. In 2004, Professor J.W. Yeh and his group first reported a new approach to alloy design, which involved mixing elements in equiatomic or near-equiatomic proportions, to form multi-component alloys with no single principal element. These alloys are expected to have high configurational entropy and hence were termed as "high entropy alloys." HEAs have a broad range of structures and properties, and may find applications in structural, electrical, magnetic, high-temperature, wear-resistant, corrosion-resistant, and oxidation-resistant components. Due to their unique properties, high entropy alloys have attracted considerable attention from both academics and technologists. This book presents the fundamental knowledge present in the field, the spectrum of various alloy systems and their characteristics studied to date, current key focus areas, and the future scope of the field in terms of research and technological applications.

The demands on materials to perform under complex service conditions has necessitated rapid advances in the design and development of materials and associated technologies. Development of new concepts starting at the electronic structure of materials and their modeling require application of advanced computer tools and software. There has been significant progress, not only in the development of advanced materials, but also in understanding their constitution and behavior with the help of modeling. This book presents a comprehensive view of the latest developments and experimental work on both these fronts and attempts to give direction to future work.

The information contained in this book deals with topics such as materials challenges in the nuclear power sector, materials science approaches in biology and medicine, Fe-and Co-based bulky glass alloys for magnetic applications, smart composites, multilayer semiconductor devices, atomic structure and interfaces, design of light alloys, superalloys, novel materials with optimized design at atomic scale, design tools for nano-and micro scale metallic materials, component design and industrial ecology, microstructural development of advanced ferritic steels, diamond/carbide nanocomposite gradient films, magnetic nanofluids, stability issues in nanostructured materials, the design of materials for enhanced tribological performance, solid oxide fuel cells, metal foams and high performance steels through nano-structures.
