GROWTH OF Al3Fe IN Al – 2.0% Fe EUTECTIC ALLOY UNDER UNIDIRECTIONAL SOLIDIFICATION

Abstract

Abstract: Effect of growth velocity and Mn on the growth of eutectic Al3Fe is investigated with help of unidirectional solidification techniques. It is found from the experimental results that the morphology of eutectic Al3Fe changes from plate-like to degenerated eutectics, to plate-like, to needle plate-like, and to needle-like. The morphology of eutectic Al3Fe changes from plate-like, needle plate like to Chinese characters-like, dendritic-like after Mn addition. The formation of eutectic Al3Fe with different shapes is also discussed.

Key words: Eutectic Al – Fe alloy, Growth, Morphology, Unidirectional solidification
