Inverse Segregation for a Unidirectional Solidification of Aluminum-Copper Alloys
A mathematical model has been developed to simulate the inverse segregation for a unidirectional solidification of Al-Cu alloys cooled from the bottom. It is found from the present study that the fluid flow of solute-rich liquid in the mushy zone caused by solidification shrinkage is the main driving force for the formation of inverse segregation. The predicted copper concentration in the solidified alloys is in good agreement with the published experimental data. Several interesting transient behaviors of solute redistribution in the mushy zone, which were not reported before, are also discussed. © 1993.
