Abstract

Abstract: Convection and constitution variation of liquid metal during solidification has been studied us- ing NH_4Cl aqueous solution.The liquid in mushy zone attached to the side wall of the mold will flow upward and form a low concentration region,in which no significant convection oc- curs,on the top of liquid zone.This region develops downward gradually during solidification. Addition of adequate component may suppress the formation of this region.

Key words: liquid zone, mushy zone, convection, constitution variation
