| Abstract: | A new technology for homogeneous solidified structure of conventional casting ingot of different-density alloys treated with an electromagnetic-mechanical field was presented. The effect of electromagnetic-mechanical field on solidified structure of conventional casting ingot of Al-20Sn alloy was studied, and the theoretical analysis was conducted. The results showed that: at the semi-solid range, the lower the treating temperature, the smaller the difference of solidified structure at different positions of the conventional casting ingot. |
