Functionally Graded Materials (FGM) has served as a unifying theme for interdisciplinary research for more than a decade. The biannual International Symposium on Functionally Graded Materials has provided a forum for research on materials with spatial variation in microstructures or chemistries and have brought together a small, but richly interactive, community of FGM researchers from university, industry, and government labs all around the world. This new volume brings to readers current advancements and information on the topic of Functionally Graded Materials. More than 150 researchers from 20 different countries came together in Estes Park, Colorado for FGM 2000 to bring this information to the rest of the research world. FGM continues to be a vigorous topic stimulating new materials research, and this proceedings will keep you informed of all the latest developments in this area. Proceedings of the 6th International Symposium on Functionally Graded Materials, Estes Park, Colorado, USA, September 10-14, 2000; Ceramics Transactions, Volume 114.
