Outline of Final Research Achievements

An UV optical microscopic system for high temperature observation to from room temperature to 1400℃ free from the effect of thermal radiation is developed using a band-pass filter and UV illumination. Random pattering method for stable micro-pattern available to 1400℃ in digital image correlation is established. Coefficient of thermal expansion of polycrystalline Al2O3 is measured at high temperature using the developed system. A system for applying load to the sample at high temperature is developed. It has been proven that the non-uniform thermal strain is induced in a single complete weave of woven fiber-reinforced ceramics.
