摘要：
An analytical solidification "model has been coupled with the local solute redistribution equation proposed by Flemings and Nereo, permitting a complete analytical description of the positional variation of the segregation as a function of solidification thermal parameters. The theoretical predictions were compared with the experimental inverse segregation profile of a vertical directionally solidified Al-6.2 wt.% Cu ingot.
