Definitions
- Mg-containing high-silicon aluminum alloys with relatively high plasticity and strength, including profiles, bars, sheets, and forgings, for use as advanced new structural materials.
- the present invention presents the aluminum alloys containing Mg and high Si, which comprises profiles, bars sheets, and forgings, wherein the aluminum alloys are made by a process as defined in the claims, comprising the steps of:
- the Mg-contained high-silicon aluminum alloys may contain at least one of Cu, Zn, Ni, Ti, and Fe elements, wherein a total weight percentage of the Cu, Zn, Ni, Ti, and Fe is less than 2wt%.
- the heat treatment is applied to the product at a predetermined temperature.
- a plurality of parameters of the hot extrusion, hot rolling, and hot forging processes are shown in Figs. 20, 21 , and 22 respectively.
- a plurality of mechanical properties of the alloys after the heat treatments is shown in Fig. 23 .
