Research Abstract

Fundamental equations are derived for the stress measurement in single crystals using monochromatic X-rays and white X-rays. Two-dimension detectors are necessary for measurements with high precision. A two-dimensional detector, PILATUS, was confirmed to be usable for stress measurement using synchrotron X-rays. Stress values measured in each grain around SCC and fatigue cracks in nickel-base alloy have large variation, and was expected to have a big influence on the propagation behavior of grain-size order cracks.
