Effect of pre-homogenization deformation treatment on the workability and mechanical properties of AlMg5Si2Mn alloy

This study evaluated the effect of a novel treatment method on the potential application of AlMg5Si2Mn die casting alloy as a substitute for wrought aluminum alloy in products. The proposed pre-homogenization deformation treatment was intended to increase the hot workability of the AlMg5Si2Mn alloy, which is typically not malleable due to the presence of interconnected brittle phases. By disintegrating interconnected eutectic Mg2Si phases into fragmented particles, the slight cold rolling before homogenization significantly enhanced hot rolling workability. Rolled sheets were successfully fabricated by hot and subsequent cold rolling, and the sheets exhibited enhanced mechanical properties compared to cast samples.
