摘要：

Effects of Mg on the microstructure and properties of forged 6000 series aluminium alloy (Al-xMg-0.95Si-1.02Cu-0.33Mn-0.015Sr-0.21Zr, percentage of mass) were studied by means of XRD and EBSD analysis, tensile property test, hardness and conductivity test, inter-granular corrosion experiments. With the increase of Mg content, dislocation strength, tensile strength and ductility of the alloy show a trend of rising first and then falling. When Mg content is 1.04 wt%, the alloy has the best comprehensive properties, with strength reaching 412.48 MPa and elongation reaching 13.56%, and the intergranular corrosion resistance of the alloy deteriorates with the increase of Mg content. At the same time, the higher the ratio of the low-angle grain boundaries in the 6000 series aluminum alloy, the lower the inter-corrosion ability.
