Polymer Phase Diagrams


Book Description

Polymeric materials include plastics, gels, synthetic fibres, and rubbers. They are all-important both in industry and in daily life. Unlike liquid water, ice, or sugar solution, polymers are not homogeneous. They are said to consist of two or more phases, and their production and processing, as well as their properties and uses, depend on an understanding of the transitions that take place between these phases. This new textbook uses fundamental principles to classify phase separation phenomena in polymer systems, and describes simple molecular models explaining the observed behaviour.




Phase Diagrams 6-V


Book Description

Phase Diagrams: Materials Science and Technology, Volume V is a six-chapter text that covers the use of phase diagrams in the understanding and development of inorganic materials. This volume first examines the atomistic understanding of the geometry of phase diagrams and the thermodynamic parameters on which the diagrams are based, as well as the relations of diagrams to crystal chemistry. The topics are followed by discussions on the most important thermodynamic theories of nonstoichiometry in binary oxide systems and the theories of spinodal decomposition that are relevant to crystalline nonmetals, especially to mixed crystalline oxides. Other chapters explore the phase equilibrium relations of phosphatic apatites including fluor-, chlor-, and hydroxyanion-containing compounds and of sialons and other nitrogen ceramics. The last chapter describes the mechanical, chemical, and thermal shock-resistant properties required of materials for stringent application. This chapter highlights the maximizing of the thermal shock resistance of silicate ceramics through lowering thermal expansion to meet the required properties of this application. The use of phase diagrams in the development of low thermal expansion materials for these applications is also discussed. This book will be useful to all scientists, engineers, and materials science students who are investigating and developing materials, as well as to the end user of the materials.




Introduction To Phase Diagrams In Materials Science And Engineering


Book Description

'… the author uses color drawings in two-dimensions (2D) and three-dimensions (3D) to help the reader better understand what is happening in the phase diagram. Examples of ternary compounds include important alloys such as stainless steels (Fe-Cr-Ni). These illustrations greatly help one to visualize important points described in each diagram and clarifies difficult processes by also including a step-by-step description of key points through the graph … For material scientists and engineers who need to understand phase diagrams, this book can provide you with that basic knowledge that will make you an expert at reading these sometimes very complicated graphs.'IEEE Electrical Insulation MagazinePhase diagrams are a MUST for materials scientists and engineers (MSEs). However, understanding phase diagrams is a difficult task for most MSEs. The audience of this book are young MSEs who start learning phase diagrams and are supposed to become specialists and those who were trained in fields other than materials science and engineering but are involved in research and/or development of materials after they are employed.Ternary phase diagrams presented in Chapter 4 are far more complex than binary phase diagrams. For this reason, ternary phase diagrams are nowadays less and less taught. However, in ceramics and semiconductors ternary phase diagrams become more and more important. Recent software provides necessary information to handle ternary phase diagrams. However, needless to say, without fundamental knowledge of ternary phase diagrams it is impossible to understand ternary phase diagrams correctly. In this book ternary phase diagrams are presented in a completely original way, with many diagrams illustrated in full color.In this book the essence of phase diagrams is presented in a user-friendly manner. This book is expected to be a Bible for MSEs.




Phase Diagrams 6-III


Book Description

Phase Diagrams: Materials Science and Technology, Volume III is an eight-chapter text that deals with the use of phase diagrams in electronic materials and glass technology. This volume first describes several crystal-growth techniques and the use of phase diagrams in crystals grown from high-temperature systems. This is followed by discussions on phase problems encountered in semiconductor studies with compound semiconductors and the use of phase diagrams in illustrating superconducting state and superconductivity property of materials. A chapter deals with the preparation of metastable phases by rapid quenching from the liquid (splat cooling) and the alloy constitution changes associated with their formation and properties, with a particular emphasis on the phase-diagram representation of metastable alloy phases. The discussion then shifts to metastable liquid immiscibility, occurrence, techniques of study, mechanisms of microphase separation, phase diagrams, and practical applications. This volume also examines the use of phase diagrams to obtain solubility data for high-temperature systems assisting in the prediction of dissolution behavior. The concluding chapters explore the relationships between phase diagrams and the structure of glass-forming oxide and phase studies of molten salts and their interactions with other salts and oxides. This book will be useful to all scientists, engineers, and materials science students who are investigating and developing materials, as well as to the end users of the materials.




Phase Diagrams 6-II


Book Description

Phase Diagrams: Materials Science and Technology, Volume II covers the use of phase diagrams in metals, refractories, ceramics, and cements. Divided into 10 chapters, this volume first describes the main features of phase diagrams representing systems in which the oxygen pressure is an important parameter, starting with binary systems and proceeding toward the more complicated ternary and quaternary systems. The subsequent chapters discuss the application of phase diagrams in several refractory systems. A chapter covers the procedures used for cement production and some of the available phase-equilibrium data and their application to specific situations. This volume also deals with the application of phase diagrams to extraction metallurgy, with an emphasis on oxide systems, as well as in ceramic and metal sintering. The concluding chapters explore the relationship of heat treatment of metals and alloys to their phase diagrams. These chapters also deal with the use of phase diagrams in several techniques of joining metals, such as fusion welding, brazing, solid-state bonding, and soldering. This volume will be useful to all scientists, engineers, and materials science students who are investigating and developing materials, as well as to the end users of the materials.

The Boundary Theory of Phase Diagrams and Its Application


Book Description

The Boundary Theory of Phase Diagrams and Its Application -- Rules for Phase Diagram Construction with Phase Regions and Their Boundaries presents a novel theory of phase diagrams. Thoroughly revised on the basis of the Chinese edition and rigorously reviewed, this book inspects the general feature and structure of phase diagrams, and reveals that there exist actually two categories of boundaries. This innovative boundary theory has solved many difficulties in understanding phase diagrams, and also finds its application in constructing multi-component phase diagrams or in calculating high-pressure phase diagrams. Researchers and engineers as well as graduate students in the areas of chemistry, metallurgy and materials science will benefit from this book. Prof. Muyu Zhao was the recipient of the 1998 Prize for Progress in Science and Technology (for his work on the boundary theory of phase diagrams) awarded by the National Commission of Education, China, and many other prizes.
