The objective of this research project is to investigate the fundamental mechanical properties of the metal-ceramic interface, and to relate those properties to the atomic structure of interface. Until this point we have emphasized the development of innovative techniques for (i) measuring the shear strength of the interface, and (ii) the interfacial energy of the metal-ceramic interface. In the present phase these techniques are being applied to model metal-ceramic systems. The ultimate shear strength of the silica-copper interface has been measured to be in the range 570 MPa to 1670 MPa. This interface had been suspected to be strong but these are the first quantitative measurements of its shear strength. The interfacial energy of the interface is being measured by measuring the contact angle between the metal and the ceramic. It has been found that poor wetting between the copper-alumina interface causes the copper film to become unstable and break up into small spheres. Keywords: Interfaces, Metal-ceramic, Composites.

As engineering materials and structures often contain a metal or metallic alloy bonded to a ceramic, the resultant interface must be able to sustain mechanical forces without failure. They also play an important role in oxidation or reduction of materials. The workshop on 'Bonding, Structure and Mechanical Properties of Metal/Ceramic Interfaces' was held in January 1989 within the Acta/Scripta Metallurgica conference series. It drew together an international collection of 70 scientists who discussed a wide range of issues related to metal-ceramic interfaces. The sessions were divided into 7 categories: structure and bonding, chemistry at interfaces, formation of interfaces, structure of interfaces, thermodynamics/atomistics of interface fracture, mechanics of interface cracks, and fracture resistance of bimaterial interfaces. Within these headings attention was paid to grain boundaries, the influence of chemical processes on the behaviour of interfaces, diffusion bonding, characterization of fracture, and crack propagation by fatigue and by stress corrosion. The book presents a useful reference source for materials scientists, physicists, chemists, and mechanical engineers who are concerned with the roles and properties of interfaces.

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.

Advanced ceramics cover a wide range of materials which are ceramic by nature but have been developed in response to specific requirements. This encyclopedia collects together 137 articles in order to provide an up-to-date account of the advanced ceramic field. Some articles are drawn from the acclaimed Encyclopedia of Materials Science and Engineering, often revised, and others have been newly commissioned. The Concise Encyclopedia of Advanced Ceramic Materials aims to provide a comprehensive selection of accessible articles which act as an authoritative guide to the subject. The format is designed to help the readers form opinions on a particular subject. Arranged alphabetically, with a broad subject range, the articles are diverse in character and style, thereby stimulating further discussion. Topics covered include survey articles on glass, hot pressing, insulators, powders, and many are concerned with specific chemical systems and their origins, processing and applications. The Concise Encyclopedia of Advanced Ceramic Materials will be invaluable to materials scientists, researchers, educators and industrialists working in technical ceramics.
