Available in PDF, EPUB and Kindle. Book excerpt: Since the benefit of stress-induced tetragonal to monoclinic phase transformation of confined tetragonal zirconia particles was first recognized in 1975, the phenomenon has been widely studied and exploited in the development of a new class of materials known as transformation toughened ceramics (TTC). In all materials belonging to this class, the microstructure is so controlled that the tetragonal to monoclinic transformation is induced as a result of a high applied stress field rather than as a result of cooling the material below the martensitic start temperature. The significance of microstructure to the enhancement of thermomechanical properties of TTC is now well understood, as are the mechanisms that contribute beneficially to their fracture toughness. The micromechanics of these mechanisms have been extensively studied and are therefore presented here in a cogent manner. The authors also review dislocation formalism for the modelling of cracks and Eshelby's technique. In compiling this monograph the authors present the most up-to-date and complete review of the field and include several topics which have only recently been fully investigated.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to provide a coherent and up-to-date discussion of the scientific work concerning the transformation toughening of ceramics. We hope the book is useful to scientists, engineers and students who are new to these materials. It is intended both as a source of learning and information to those who are new to these materials. It is intended both as a source of learning behaviour and microstructural relationships in transformation-toughened ceramics. While it has been our aim to present a book that is current as possible at the time of publication, the subject is still expanding in many areas; so our hope is that the reader will also gain an insight into the direction of future advances.

Available in PDF, EPUB and Kindle. Book excerpt: This book contains the lectures of the 5th Advanced Seminar on Fracture Mechanics (ASFM 5) held at the Joint Research Centre, Ispra, on 14-18 October 1985. The series of the ASFMs is one of the two main regularly scheduled international events sponsored by the European Group on Fracture (EGF) , alternating with the European Conferences of Fracture (ECFS). Whereas ECFs are held in a different place on even years (the last. ECF6,was in Amsterdam in June 1986), ASFMs are hosted at the JRC Ispra on odd years. This establishment belonging to the Commission of the European Communities performs research work of common interest to the EC Member countries. One of the activities of the JRC-Ispra is the organization of Ispra-Courses aiming at the transfer of knowledge and the strengthening of exchanges and ties between European scientific workers. ASFMs are designed to give an advanced level treatment in selected areas of fracture mechanics. Previous ASFMs had been devoted to elastic-plastic fracture mechanics and to subcritical crack growth due to fatigue, stress corrosion and creep. In the early stages of preparation of ASFM5 it was decided to concentrate on a new theme, the fracture phenomena and fracture mechanics of non-metallic materials. Whereas fracture mechanics started with the study of glass by Griffith, its later developments centered predominantly on metallic alloys. However, in recent years non-metallic materials have found increasing uses and correspondingly efforts have been made to develop testing and prediction methods for these materials.

F. Lange and published by . This book was released on 1980 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thermodynamics of the constrained phase transformation is presented with particular reference to size effects introduced by surface phenomena concurrent with the transformation, e.g., the formation of solid-solid surfaces (twins, etc.) and solid-vapor surfaces (e.g., microcracks). It is shown that these surface phenomena not only introduce a size-dependent energy term into the total free energy change, but also reduce the strain energy associated with the transformation, which can result in a transformation at a temperature where the chemical free energy change is less than the unrelieved strain energy associated with the constrained transformation. The results of this analysis lead to a phase diagram representation that includes the size of the transforming inclusion. This diagram can be used to define the critical inclusion size required to prevent the transformation and/or to obtain the transformation, but avoid one or more of the concurrent surface phenomena.

Download or read book Martensitic Transformation written by Zenji Nishiyama and published by Elsevier. This book was released on 2012-12-02 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Martensitic Transformation examines martensitic transformation based on the known crystallographical data. Topics covered range from the crystallography of martensite to the transformation temperature and rate of martensite formation. The conditions for martensite formation and stabilization of austenite are also discussed, along with the crystallographic theory of martensitic transformations. Comprised of six chapters, this book begins with an introduction to martensite and martensitic transformation, with emphasis on the basic properties of martensite in steels such as carbon steels. The next two chapters deal with the crystallography of martensite and discuss the martensitic transformation behavior of the second-order transition; lattice imperfections in martensite; and close-packed layer structures of martensites produced from ? phase in noble-metal-base alloys. Thermodynamical problems and kinetics are also analysed, together with conditions for the nucleation of martensite and problems concerning stabilization of austenite. The last chapter discusses the theory of the mechanism underlying martensitic transformation. This monograph will be of interest to metallurgists and materials scientists.

Lange and published by . This book was released on 1979 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three A1203/ZrO2 composites series, containing 0, 2, and 7.5 mole % Y203, respectively, were fabricated. For the A1203/ZrO2(+2M/oY203) series, tetragonal ZrO2 was retained from one end-member to the other. Significant increases in fracture toughness and strength were observed for materials in this system. Strengths decreased with increasing temperature. These results are consistent with previous theoretical predictions. (Author).
