Effects of Deformation Mechanisms on Texture Evolution and Mechanical Response of the Mg-1Al-0.5Mn-0.3Gd Alloy Under Plane Tension

The tensile plastic deformation of the Mg-1Al-0.5Mn-0.3Gd alloy with transverse direction (TD)-tilted texture have been investigated using the experimental and visco-plastic self-consistent model. The results show that the relative activity of the different deformation mechanisms of the magnesium alloys with TD-tilted texture is related to different tensile mechanical properties and the texture evolution under the tensile plastic deformation is in the rolling direction and TD. Moreover, the tensile mechanical behavior of the magnesium alloys with TD-tilted texture has been further studied by inhibiting the activity of different deformation mechanisms in the TD, which shows that, at the early stage of the tensile plastic deformation, the basal slip has the greatest influence on the magnesium alloy with TD-tilted texture. In addition, the pyramidal slip plays an important role with the greatest influence on the mechanical properties of magnesium alloys with TD-tilted texture at the later stage of tensile plastic deformation.
