| Abstract: | The influence of RE element on aluminum alloy microstructure was discussed, and the preparation process for semi-solid billet was researched.Experiments show that adding the RE element refines the grain of aluminum alloy.Slope-liquidus method can be used to prepare excellent semi-solid billet, its remelting microstructure is uniform, small equiax crystal, its thixotropy is better and the remelting process is more simple.So Al-Si alloy with RE element has excellent semi-solid performance and great values. |
