In the present study, complex modification of primary and eutectic Mg2Si particles in Al-15%Mg2Si, composite was examined by simultaneous addition of gadolinium (Gd) and antimony (Sb). It was realized that combined addition of 1.5 wt. % Gd-Sb was efficient for modifying Mg2Si, in which coarse dendri...
