Paper Title:
Experimental Research on Grain Orientation Evolution of Extruded Mg Alloy AZ31B Sheet during Uniaxial Tensile Deformation
  Abstract

The orientation rotation in extruded Mg alloy AZ31B sheets during uniaxial tension at room temperature has been investigated using SEM/EBSD technique. According to the experimental results and the calculated results of Sachs crystal model, the quantitative rule of the tensile axis rotation for the grains (parent), and the associated slip systems have been analyzed in detail. The influencing factors of twinning area fraction have also been studied. The results show that the rule of the rotation of tensile axis can be explained by cross slip systems; the grains with different initial orientations exhibit different twinning behaviors; the area fractions of extensive twins have a close relationship with Schmid factors of tensile twinning, and with the angle between c-axis and tensile axis of the grains.
