Abstract:
      The effects of trace Zr on microstructure and properties of Al-0.8Mg-0.9Si alloy sheets by asymmetrical rolled and its subsequent solution treated were investigated. The results show that the Al3Zr phase is formed in the alloy and dispersed in the matrix. The phases has unobvious effect on the formation of deformation textures Copper{112}<111>, Brass{011}<211>, S{123}<634>, E{111}<110>, F{111}<112> and others during asymmetric rolling process. However, the recrystallization happened during the subsequent solution treatment makes the orientation density of the textures Copper, Brass, S etc. reduce ,while the density of shear textures E and F formed in the asymmetric rolling process enhance due to the insoluble fine phase Al3Zr inhibit recrystallization process to some extent. The structure of trace elements Zr promote plates of the alloy a better comprehensive properties which the tensile strength, yield ratio and elongation were up to 230MPa, 0.49 and 9.5%, respectively, the plastic strain ratio r value increased from 0.7 to 0.84, the value of cup drawing IE increased from 8.94 to 9.84, and the anisotropy degree of ∣Δr∣reduced from 0.15 to 0.04.
