X-Ray Stress Measurement of Austenitic Stainless Steel with cosα Method and Two-Dimensional X-Ray Detector

Abstract:

This paper describes a fundamental experiment on X-ray stress measurement of austenitic stainless steel (JIS SUS316L) with a new equipment which was developed in this study. An image plate (IP) as a two-dimensional X-ray detector and the cosα method as a principle of the measurement of stress were used in it. An experiment was conducted with CrKβ characteristic X-ray and γFe-311 diffraction line, and the results were compared to those that were obtained with the conventional sin²ψ method under the similar X-ray conditions. It was found that the accuracy of stresses obtained with the equipment developed are almost as same as those of the sin²ψ method. However, the measuring time can be shorten by several times by using it.
