This study examines the impact of the rare earth oxide La 2 O 3 on the microstructure, mechanical and corrosion resistance properties of as-cast Al-Si-Mg (A356) alloys, with a specific focus on the A356 alloy. By incorporating varying amounts of La 2 O 3 (0 wt%, 0.2 wt%, 0.3 wt%, and 0.4 wt%) into the A356 alloy, four samples (AL0, AL2, AL3, and AL4) were produced. The findings demonstrate that an optimal addition of La 2 O 3 (0.3 wt%) can effectively reduce the secondary dendrite arm spacing (SDAS), refine the eutectic Si phase, and modif...
