Science and Technology of Interfaces: International Symposium in Honor of Dr. Bhakta Rath



The International Symposium was organized to capture the state of our knowledge on the science and technology of interfaces. The Symposium (in honor of Dr. B. B. Rath) was held during the TMS Annual meeting, Feb 17-21, 2002 at Seattle WA. This volume captures the salient papers presented at the symposium. The symposium was sponsored by the Structural Materials Division and the Electronic, Magnetic & Photonic Materials Division of TMS and the Materials Science Critical Technology Sector of ASM International and in particular by the following committees: the Physical Metallurgy Committee (TMS), the Superconducting Materials Committee (TMS), the Titanium Committee (TMD) and the Mechanical Behavior of Materials Committee (TMS/ASM). The objective of this symposium was to present current research on advanced interface controlled materials with primary focus on advanced materials. Special attention was given to design of such interface controlled materials with their unique and highly desirable properties. The symposium was designed to assess the current status and to identify future directions of research, design and applications of the role of interfaces in nanostructured bulk solids, films and coatings as well as polycrystalline superconducting materials. Particular emphasis was placed on developing close interactions and fostering future collaborations among scientists and engineers from the USA, Western and Eastern Europe, Russia, and other Asian countries.
