    Abstract
  • The microstructures and tensile properties of cold-rolled and T3 treated 2524 aluminum alloy sheet with the thickness of 2mm at different orientation were investigated by tensile test,OM,XRD and TEM analysis.On the basis of the model that regards the sheet containing only {110}texture,the relationship of in-plane anisotropy and the anisotropy of crystallography was analyzed.The results show that the strength of 2524 cold-rolled and T3 sheet orientated 45° and 60° with respect to the rolling direction is lower than that of specimens orientated 0°,30° and 90° with respect to the rolling direction.The elongation of the sheet orientated 45° with respect to the rolling direction is highest,And then the tensile properties of the sheet orientated 0° with respect to the rolling direction are both higher than that of the sheet orientated 90° with respect to the rolling direction.The IPA of cold-rolling condition alloy sheet is higher than that of T3 condition.The major crystallographic texture of 2524 cold-rolled sheet is {110},and the secondary crystallographic texture is {311}.But the major crystallographic texture of 2524-T3 condition is {110}.The in-plane anisotropy of mechanical properties of 2524 aluminum alloy sheet is closely related to the grain structure and crystallography orientation,among them crystallographic texture is responsible for the in-plane anisotropy of mechanical properties.
