Notes:
Al-Mg-Si based alloys have been developed to produce an advanced feedstock materialfor thixoforming. Effects of excess Si, Mn addition and deformation on microstructure evolutionsduring reheating and partial remelting were studied. The homogenized microstructures of the MnaddedAl-Mg-Si alloys consist of the Al12Mn3Si2 intermetallic compound along grain boundaries ofequiaxed grains with fine-spherical and needle-like morphologies. The deformation by cold-rollinghas a strong effect on the semi-solid microstructures of the Mn-added Al-Mg-Si alloys comparedwith the balanced and excess Si alloys. The Mn-added Al-Mg-Si alloys exhibit good features toproduce the feedstock material for thixoforming
