초록

A Solidification of the aluminum was studied under the condition of the forced liquid convection. The Al melt was stirred by a highly rotating carbon bar on whose surface the solidified Al was nucleated. The Al was refined by partial solidification and the solute distributions were rationalized through the estimation of the solidification rate which is based on the heat transfer calculation of the process. The microstructure-morphological change of the specimens was also showed.
