Functionally graded materials in the 21st century : a workshop on trends and forecasts, [which was held on March 26 to 28, 2000, at Epochal Tsukuba International Congress Center, Tsukuba, Japan

I am honored to chair this International Workshop on Functionally st Graded Materials in the 21 Century: A Workshop on Trends and Forecasts, and would like to first express my sincere gratitude to everyone participating. The Mechanical Engineering Laboratory and the Japan International Science and Technology Exchange Center (JISTEC) have co-organized this workshop with the sponsorship of the Science and Technology Agency of Japan and the cooperation of the Association of Mechanical Technology. This workshop is an international conference to focus on functionally graded materials and the aim is to provide an overview of the present global technical trends and the future development of functionally graded materials over the next 10 years. I am very happy to see many researchers meeting together here - including seven researchers invited from abroad. During the three-day oral sessions, 36 research reports will be presented, and I'm sure I'm not the only one who is very anxious to hear and participate in the upcoming interesting discussions. At present, the Mechanical Engineering Laboratory is conducting fundamental and ground-breaking research in such major areas as materials science and technology, bioengineering, information & system science, advanced machine technology, energy technology, manufacturing technology and robotics. In particular, we consider research on materials science and technology to have the highest priority for the 21st century. and since 1996 have participated in the US-Japan joint research project, Precompetitive Processing and Characterization of Functionally Graded Materials. "In a Functionally Graded Material (FGM), which is a kind of advanced composite materials, the composition and structure change gradually over volume, resulting in corresponding changes in the properties of the material. By appyling the possibilities inherent in the concept of FGM, it is anticipated that materials will be improved and new functions for them will be also created. A comprehensive description of status of the art and perspectives, modeling and simulation, processing and system, characterization of properties as well as applications of FGMs is covered in this book."--Jacket Front Matter....Pages i-xvi Introduction....Pages 1-26 Modeling and Simulation....Pages 27-51 Processing and System....Pages 53-102 Characterization of Properties....Pages 103-205 Applications....Pages 207-235 Back Matter....Pages 237-242 "This book is the proceedings of an international workshop on "Functionally Graded Materials in the 21st Century: A Workshop on Trends and Forecasts", which was held on March 26-28, 2000, in Tsukuba, Japan." Direct bonding of metals and ceramics can generate thermal stresses in practical high-temperature applications which are due mainly to CTE mismatches.
