Research Abstract

In order to develop highly-reliable maintenance systems, analytical and diagnostic techniques for fatigue damage characterization should be improved further. In the present study, various researches have been performed to solve the problems which have been required to develop the maintenance systems for quantitative fatigue damage evaluation by electron backscatter diffraction techniques. The major findings of this study indicated that not only various data analysis was effective but also further improvement of measurement accuracy should be required for the development of the systems.
