In situ synchrotron X-ray micro diffraction study of deformation behavior in polycrystalline coppers during uniaxial deformations

The deformation behavior of pure copper polycrystals was investigated by in situ X-ray microdiffraction using synchrotron radiation. Tensile axis rotations of several positions of same grain were observed. Tensile axis movement depends on local position of a grain. This phenomenon may originate from the orientation relation between neighboring grains. (C) 2004 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.X1110sciescopu
