Book Synopsis Interfaces in Crystalline Materials by : Adrian P. Sutton

Download or read book Interfaces in Crystalline Materials written by Adrian P. Sutton. This book was released on 1995. Available in PDF, EPUB and Kindle. Book excerpt: The study of interfaces within and between materials is a central field which is relevant to almost all aspects of materials science. For example, interfaces play a role in many of the mechanical and electrical properties of materials, phase transformations, and microstructure of materials. This book is intended to serve as a graduate text consisting of four inter-related parts spanning the structure, thermodynamics, kinetics, and properties of interfaces in crystalline materials. Throughout the book emphasis is placed on the conceptual foundations of the subject through the exposition of simple models and descriptions of key experimental observations. In this way the reader is gradually taken to the forefront of the subject. The first four chapters deal with structural aspects of interfaces-interfacial geometry, dislocation models, interatomic forces, and atomic structure. There are three chapters dealing with thermodynamic aspects of interfaces; the thermodynamics of interfaces; interfacial phases and phase transitions, and segregation of solute atoms. The kinetics of interfaces are covered in three chapters concerned with diffusion, conservative motion, and non-conservative motion. Finally there are two chapters which cover the electrical and mechanical properties of interfaces. This book is a unique introduction to the field of interfaces in crystalline materials spanning the subject in a coherent and pedagogical style. Book jacket.

Available in PDF, EPUB and Kindle. Book excerpt: Solid interfaces such as surfaces and grain boundaries (GBs) play a very important role in the structural, mechanical, and electronic properties of materials. Using a variety of advanced computing and simulation techniques coupled with robust embedded-atom method potentials, a range of solid interfaces are explored using the intermetallic compound nickel-aluminum as a model structural material and copper and gold as model electronic materials. Low-index surfaces in NiAl for the stoichiometric and Ni-enriched cases are investigated by grand canonical Monte Carlo (MC) simulations. Surface re-ordering and segregation is observed. Surface stresses and surface segregation in (110) NiAl free-standing thin films have been studied using MC simulations. The size effect of segregation at the surface is explained by the elastic deformation of the film in response to the surface stress. Grain boundary structure and segregation at Sigma3 GBs in NiAl using stoichiometric and Ni-rich compositions are studied by molecular statics and MC simulations. Ni-segregation is observed, resulting in transformation of the GBs to structures capable of accommodating higher Ni concentrations. The full range of possible inclinations in the family of Sigma11 [110] asymmetric tilt grain boundaries in copper is investigated and structural trends are established. Development of a non-Sigma11, low-index boundary is observed, giving rise to local rotation of the GB tilt angle accommodated by development of intrinsic stacking faults. A more general case of the 9R structure in low stacking fault energy materials is postulated. MD simulation of the family of 〈110〉 90° asymmetrical tilt GBs in gold are presented and compared with high-resolution transmission electron microscopy observations of the same boundaries. The faceting behavior for this family of GBs is explored and it is shown that varying the inclination angle produces a variety of faceting behaviors.

Book Synopsis Structure and Bonding in Crystalline Materials by : Gregory S. Rohrer

Download or read book Structure and Bonding in Crystalline Materials written by Gregory S. Rohrer. This book was released on 2001-07-19. Available in PDF, EPUB and Kindle. Book excerpt: One of the motivating questions in materials research today is, how can elements be combined to produce a solid with specified properties? This book is intended to acquaint the reader with established principles of crystallography and cohesive forces that are needed to address the fundamental relationship between the composition, structure and bonding. Starting with an introduction to periodic trends, the book discusses crystal structures and the various primary and secondary bonding types, and finishes by describing a number of models for predicting phase stability and structure. Containing a large number of worked examples, exercises, and detailed descriptions of numerous crystal structures, this book is primarily intended as an advanced undergraduate or graduate level textbook for students of materials science. It will also be useful to scientists and engineers who work with solid materials.

Book Synopsis Elements of Structures and Defects of Crystalline Materials by : Tsang-Tse Fang

Download or read book Elements of Structures and Defects of Crystalline Materials written by Tsang-Tse Fang. This book was released on 2018-01-25. Available in PDF, EPUB and Kindle. Book excerpt: Elements of Structures and Defects of Crystalline Materials has been written to cover not only the fundamental principles behind structures and defects, but also to provide deep insights into understanding the relationships of properties, defect chemistry and processing of the concerned materials. Part One deals with structures, while Part Two covers defects. Since the knowledge of the electron configuration of elements is necessary for understanding the nature of chemical bonding, it is discussed in the opening chapter. Chapter Two then describes the bonding formation within the crystal structures of varied materials, with Chapter Three delving into how a material's structure is formed. In view of the importance of the effects of the structure distortion on the material properties due to the fields, the related topics have been included in section 3.4. Moreover, several materials still under intensive investigation have been illustrated to provide deep insights into understanding the effects of the relationships of processing, structures and defects on the material properties. The defects of materials are explored in Part II. Chapter 4 deals with the point defects of metal and ceramics. Chapter 5 covers the fundamentals of the characteristics of dislocations, wherein physics and the atomic mechanics of several issues have been described in detail. In view of the significant influence of the morphologies including size, shape and distribution of grains, phases on the microstructure evolution, and, in turn, the properties of materials, the final chapter focuses on the fundamentals of interface energies, including single phase (grain) boundary and interphase boundary. - Discusses the relationship between properties, defect chemistry and the processing of materials - Presents coverage of the fundamental principles behind structures and defects - Includes information on two-dimensional and three-dimensional imperfections in solids
