Available in PDF, EPUB and Kindle. Book excerpt: The threshold loads and crack sizes for indentation cracking were investigated for a number of ceramics using scanning electron microscopy and acoustic emission. It was found that the cracking behavior could be predicted, using a fracture mechanics/dimensional analysis approach modified to take into account the stress field at an elastic-plastic indentation. Selected area electron channeling was used to characterize the extent of subsurface damage produced in ceramics during grinding and polishing operations. It was found that polishing damage depths can be correlated using a simple model based on a sliding elastic-plastic indenter. Finally, the effect of temperature and strain rate upon material removal and cracking threshold was analyzed, using recent experimental compressive strength and crack growth measurements as inputs to current predictive models. The results are shown to have surprising implications with regard to dynamic, high temperature indentation (particle impact). (Author).

Book excerpt: The basic processes of indentation damage in brittle ceramics have been studied. Attention has focused on the roles of material crystallography and microstructure in determining the nature of the damage pattern. Microscopy techniques, particularly transmission electron microscopy, have been used to characterize the attendant deformation and fracture of Vickers indentation sites. Strength, toughness, and wear measurements have been carried out on polycrystalline materials to ascertain how the damage characteristics influence the ensuing mechanical properties. It is concluded that material microstructure can be a crucial factor in structural design with ceramics.
Download or read book Indentation Techniques in Ceramic Materials Characterization written by Ahmad G. Solomah and published by John Wiley & Sons. This book was released on 2012-04-11 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Indentation techniques have become widely used in the characterization of brittle solids due to their simplicity, cost effectiveness, rapidness, and maybe most importantly, the indenter itself can be used as a mechanical microprobe in thin films, interfaces, grain boundaries, and nanocomposites. The papers in these proceedings cover measurement techniques, reliability of, and problems associated with this testing method. Also included is the application of nano-indentation technique, as a new frontier in brittle solids characterization, e.g., thin film and nano-composite materials. Proceedings of the symposium held at the 105th Annual Meeting of The American Ceramic Society, April 27-30, in Nashville, Tennessee; Ceramic Transactions, Volume 156.

This book was released on 2012-12-06 with total page 733 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 17th University Conference on Ceramics, which also was the 7th LBL/MMRD International Materials Symposium, was held on the campus of the University of California at Berkeley from July 28 to August 1, 1980. It was devoted to the subject of surfaces and interfaces in ceramic and ceramic-metal systems. The program was timely and of great interest, as indicated by the large number of contributed papers, which included contributions from ten foreign countries. These proceedings are divided into the following categories dealing with the chemistry and physics of interfaces: calculations of interface/surface states, characterization of surfaces and inter faces, thermodynamics of interfaces, influence of surface and inter faces on selected ceramic processes, grain boundary structures, effects of grain boundaries on deformation and fracture, interfacial phenomena, formation of interfaces, development of adhesion, and reactions at interfaces. A number of papers deal specifically with the Si-Si02 interface, which probably has received more attention than any other because of its importance in the electronics industry. This coverage fulfills the principal objective of the symposium which was to explore and assess the current fundamental understand ing of interfaces and surfaces. A parallel objective of the symposium was fulfilled by a group of papers dealing with the correlation of interfacial characteris tics with mechanical behavior. This group includes papers dealing with the adherence of dissimilar materials at interfaces.

Download or read book Transformation Toughening Of Ceramics written by David J. Green and published by CRC Press. This book was released on 2018-02-06 with total page 292 pages. 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.

This book was released on 2012-12-06 with total page 742 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume "Deformation of Ceramic Materials II" constitutes the proceedings of an international symposium held at The Pennsyl vania State University, University Park, PA on July 20, 21, and 22, 1983. It includes studies of semiconductors and minerals which are closely related to ceramic materials. The initial conference on this topic was held in 1974 at Penn State and the proceedings were published in the volume entitled "Deformation of Ceramic Materials." This conference emphasized the deformation behavior of crystals and po1ycrysta11ine and polyphase ceramics with internationally recognized authorities as keynote lecturers on the major subtopics. Several papers dealing with cavity nucleation and creep crack growth represent a major new research thrust in ceramics since the first conference. This collection of papers represents the state-of-the art of our understanding of the plastic deformation behavior of ceramics and the crystals of which they are composed. We are grateful for the suggestions of our International Advisory Committee .in recommending experts in their respective countries to participate. We are particularly grateful that the organizers of the previous Dislocation-Point Defect Interaction Workshops agreed to participate in the Penn State Symposium as an alternative at the suggestion of Prof. A. H. Heuer. We acknowledge the financial support of the National Science Foundation for this conference.
