Observation of Deformation Behavior in Magnesium Alloy AZ 31 by Diffraction Contrast Tomography Using Synchrotron Radiation

Abstract

A technique for three dimensional grain mapping of polycrystals, called X-ray diffraction contrast tomography (DCT), has been proposed and developed to evaluate damage in fatigue process. In the present study, the DCT was conducted for magnesium alloys (AZ31) to evaluate the fatigue damage during tension-compression tests, the change in misorientation of the basal plane was different from the twin plane.
