Deformation behavior and texture evolution in an extruded Mg-1Gd alloy during uniaxial compression

This paper reports the deformation behavior and texture evolution during uniaxial compression in an extruded Mg-1Gd alloy with a typical 〈2−1−11〉 fiber texture using the electron backscattering diffraction (EBSD) technique. Extension twinning and basal slip are the dominant deformation modes in the early stage of compressive deformation, which are responsible for the remarkable change of texture components. With increasing strain, the texture is changed from the 〈2−1−11〉 into the 〈0001〉 fiber texture component mainly due to the gradual rotation of c-axes towards the compressive direction caused by basal slip.
