## Abstract

The formation of banded structure with bands perpendicular to the growth direction is reported in the rapidly solidified $Al$-10at%$Mn$ alloy. The bands consist of fine quasicrystalline phases distributed alternately in the $\alpha-Al$ matrix. It is shown that this banding is different from that observed in the rapidly solidified $Ag-Cu$ alloys. A qualitative explanation based on the interplay of kinetics of solute transport and the nature of free energy curves is proposed to explain the banding in $Al-Mn$ alloys.
