Abstract
In this work the stage of cell development and the cell morphology in the Al-Zn eutectic have been studied by solidifying the alloy unidirectionally. Cells are shown to develop preferertially from grain boundaries, growth induced boundaries and fault lines. In the Al-Zn eutectic alloy, well developed regular cell shape as in solid solution has not been found, but its typical sharp is rhombic. Besides, chrysanthemum-like shape and some other shape, which seems likely deformed from any hexagonal form irregulary, has been found. At high impurity concentration. 0.52% of Cd, cellular dendrite has been produced.
