Book Description
High Temperature Oxides, Magnesia, Alumina, Beryllia Ceramics: Fabrication, Characterization and Properties is the third part of a series of four books on high temperature oxides. This text is divided into five chapters that deal with the research and technical advances in selected refractory oxides, such as magnesia, alumina, and beryllium oxide. Chapter 1 discusses the preparation, characterization, thermal and mechanical properties, and application to the electrical and electronic fields of beryllium oxide. Chapter 2 examines the mechanical behavior of single crystals of magnesia, including its dislocation motion and interactions, and crack nucleation and growth. Chapter 3 describes the significance of diffusive and mechanical properties of sintered alumina and magnesia. Chapter 4 deals with the process mechanisms, control, and limitations of hot-pressing, with particular emphasis on the practical applications of hot-pressed refractory oxides. Chapter 5 explores the possible benefits of hot-working, operational processes involved in such working, and the applications of fabricated oxides. This book is of great value to engineers, materials scientists, and students with advanced materials science courses.

On the Mechanism of Ductile Bending in Ionic Crystals
Author: Charles E. MayPublisher:
ISBN:
Category : Bending
Languages : en
Pages : 24
Book Description
This report presents experimental evidence in support of a mechanism that explains the bending of face-centered cubic ionic single crystals such as sodium chloride. When a specimen is deformed in flexure, some new dislocations are generated while others are driven from the sample; some of the remaining dislocation align themselves along the (110) slip planes to produce "orientation" domain boundaries perpendicular to the slip planes. This type of process is generally referred to as mechanical polygonization. The existence of orientation domains was confirmed by an X-ray diffraction technique. The number of domains increases with increasing deflection, and there is slight evidence that the average angle between adjacent domains may also increase with increasing deflection. An approximate value for the average angle attained between adjacent domains is about 1/4°. Observation of curvature of the fracture faces also lends support to the correctness of the model. A unique relaxation phenomenon appears to occur if a crystal is allowed to sit with a constant overall deflection; the curvature that is present apparently tends to become more uniform along the length of the specimen.
