放射光回折コントラストトモグラフィーによるマグネシウム合金AZ31の引張－圧縮過程における変形挙動の観察

抄録

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.
