Title: Graded Distribution of Microstructure in Centrifugal-Cast Al-Cu Alloys
Abstract: In the centrifugal field,the graded distribution patterns of grain size and the content of Al2Cu phase and Cu of Al-Cu alloy castings are investigated at the same centrifugal radius and different positions.The results show that the grain size and the content of Al2Cu phase and Cu in centrifugal-cast Al-Cu alloy at casting's sides are lower than that at casting's center.With increasing of the mould rotation speed,the trend of graded distribution of grain size and the content of Al2Cu phase and Cu increases.In addition,the grain size and the content of Al2Cu phase and Cu in Al-Cu alloy casting is bilateral asymmetry.
