Abstract Convection and constitution variation of liquid metal during solidifi-cation has been studied using NH_4Cl agueous solution. The liquid in mushy zoneattached to the side wall of the mold will flow upward and forms a low concen-tration region, in which no significant convection occurs, on the top of liquidzone. This region develops downward gradually during solidification. Addition ofadequate component may suppress the formation of this region.

Key words: Liguid zone mushy zone convection constitution variation
