| Description | Journal: Iop Conference Series: Materials Science and Engineering An Al-20Mg-4Si high Mg containing alloy has been produced and its characteristics investigated. The as-cast alloy revealed primary $Mg_{2}$Si particles evenly distributed throughout an α-Al matrix with a $β-Al_{3}Mg_{2}$ fully divorced eutectic phase observed in interdendritic regions. The $Mg_{2}$Si particles displayed octahedral, truncated octahedral, and hopper morphologies. Additions of Sb, Ti and Zr had a refining influence reducing the size of the $Mg_{2}$Si from 52 ± 4 μm to 25 ± 0.1 μm, 35 ± 1 μm and 34 ± 1 μm respectively. HPDC tensile test samples could be produced with a 0.6 wt.% Mn addition which prevented die soldering. Solution heating for 1 hr was found to dissolve the majority of the $Al_{3}Mg_{2}$ eutectic phase with no evidence of any effect on the primary $Mg_{2}$Si. Preliminary results indicate that the heat treatment has a beneficial effect on the elongation and the UTS. |
