Book Description
Two-phase materials are technologically important because optimum properties can be obtained by a proper combination of the two phases. Among these materials, two phase Titanium alloys are of particular interest for high temperature aerospace applications. However, there is a lack of understanding in the areas of high temperature deformation, recrystallization and grain-growth behavior of two-phase alloys in terms of the properties of the component phases. Such an understanding is essential to develop new titanium alloys with greater high temperature strength and stability for high temperature applications. The lack of understanding is due to the complex deformation behavior of these two-phase materials. Whenever a material comprising two or more phases is subjected to stress, the component phases deform differently and this results in inhomogeneous strain and stress distributions. In addition, interaction stresses develop as a result of interactions between the deforming phases. For these reasons, the deformation behavior of two-phase materials cannot be explained by the simple law of mixture rule.

Book Description
The annealing of deformed materials is of both technological importance and scientific interest. The phenomena have been most widely studied in metals, although they occur in all crystalline materials such as the natural deformation of rocks and the processing of technical ceramics. Research is mainly driven by the requirements of industry, and where appropriate, the book discusses the extent to which we are able to formulate quantitative, physically-based models which can be applied to metal-forming processes.The subjects treated in this book are all active research areas, and form a major part of at least four regular international conference series. However, there have only been two monographs published in recent times on the subject of recrystallization, the latest nearly 20 years ago. Since that time, considerable advances have been made, both in our understanding of the subject and in the techniques available to the researcher.The book covers recovery, recrystallization and grain growth in depth including specific chapters on ordered materials, two-phase alloys, annealing textures and annealing during and after hot working. Also contained are treatments of the deformed state and the structure and mobility of grain boundaries, technologically important examples and a chapter on computer simulation and modelling. The book provides a scientific treatment of the subject for researchers or students in Materials Science, Metallurgy and related disciplines, who require a more detailed coverage than is found in textbooks on physical metallurgy, and a more coherent treatment than will be found in the many conference proceedings and review articles.

Book Description
Recrystallization and grain growth, together with phase transformations such as precipitation, are the fundamental processes of microstructural evolution which take place during the thermomechanical processing of engineering materials. They are of major scientific interest and are of great importance in a wide range of industrial applications. One of the main goals of this two-volume set is to show how to cover the entire set of reactions governing recrystallization and grain growth during industrial processing - termed through process modelling. At the same time, it is important to improve the understanding of the basic mechanisms involved in transformations such as nucleation during recrystallization, grain boundary migration under the influence of various forces, and boundary interactions with solute atoms and particles. In this area, modelling plays a major - but happily not yet exclusive - role. These fundamental aspects are also treated in detail in this comprehensive work.There are also a number of papers which deal with new techniques such as laser ultrasonics and high-energy X-ray methods for characterizing deformation structures, recrystallization and grain growth during (in situ) heat treatment. The accent is increasingly placed on 3D observations of all types of crystalline solids, i.e. metals, minerals, ceramics - and now polymers. The reader will be able to find within these two volumes a wealth of up-to-date papers describing current issues, concepts, techniques and results which will, in turn, improve his understanding of recrystallization and grain growth.
