Abstract

The local stress state developed during the elastic deformation of polycrystalline Fe-17mol%Ga was measured by synchrotron white X-ray radiation, and the heterogeneity of the elastic deformation resulting from the pronounced elastic anisotropy of the Fe-Ga alloy system was examined. Tensile loading generated local stresses perpendicular to the tensile direction. The development of these stresses was discussed from the viewpoint of the interaction between grains having different elastic properties.
