Abstract
Development status of the functionally gradient materials (FGMs) which were originally introduced in Japan was summaried. A five-year project for FGMs has been sucssessfully completed.
Three groups of materials design, synthesis and evaluation established the generic technology of FGMs for relaxing the thermal stress in an environment with a maximum temperature of 2000K and a temperature difference of 1000K. The project succceded in creating small samples with 30mm of diameter and also 300mm squre panels.
