Abstract: The influence of solid fraction of Al-28Pb alloy mushy on distribution of Pb in Al-Pb ingot was studied. The special electromagnetic stirring apparatus was used to prepare Al-28Pb alloy mushy and the relationship between solid fraction and stirring temperature was gotten. The results show that when solid fraction of Al-28Pb alloy mushy is less than 45%, Pb precipitation usually happens in the ingot. However, Pb precipitation in casting reduces gradually with increasing solid fraction of mushy, and when solid fraction is larger than 45%, Pb precipitation in casting can be removed.
