This study is mainly concerned about the possibility to achieve semisolid slurry during partial solidification only through thermal and time control, that is, by In-Ladle direct thermal control (DTC) rheocasting for A206 Al alloy. This is based on the fact that there is slurry and mush transition in molten metal, which is controlled by the shape of solid and the relative energy. Thermal modeling of heat behavior with respect to ladle material and ladle design was investigated by 2-dimensional finite volume method (FVM). Based on the optimum conditions obtained by thermal modeling, microstructural evolution of A206 Al alloy by In-Ladle DTC rheocasting was carried out. Also, fluidity was investigated by actual In-Ladle DTC rheocasting for optimizing conditions of A206 Al alloy.
