Abstract

In this study, X-ray stress measurement of aluminum alloy A2017 using the Fourier analysis proposed by Miyazaki et al. was carried out. The validity of measured stresses was verified by a four point bending test. Coarsening grains existed in the specimen and spotty diffraction rings were obtained, nevertheless the Fourier analysis is applicable for such material. The stresses measured by Fourier analysis were in good agreement with both mechanical ones and the value obtained by the cosα method. For the single X-ray incident, the measured stress obtained from the 311 diffraction plane particularly showed such correspondence to applied stress as compared with the 222 diffraction plane. The reliability of stress measurement was improved by using the in-plane averaging, and it was effective for every diffraction plane. The effect of enlargement of the X-ray irradiation area saturates, thus the areas to average should be selected appropriately in order to measure the stresses efficiently.
