The microstructure and texture evolution of an AZ31 magnesium rolled sheet during quasi-static compression at strain rates of 10(-3) s(-1) has been investigated by in situ electron backscattered diffraction. The influence of the initial and pre-deformed texture on the predominant deformation mechanisms during compression has been examined. It has been found that extensive grain reorientation due to C{10-12} tensile twinning appeared when compressed along transverse direction. Tensile twin variants were observed under this loading condition, and different variants will cause an effect to the following deformation. Several twinning modes occurred with continuative loading along rolling direction. (C) 2016 Elsevier Inc. All rights reserved.
