Abstract Crystallographic characteristics and limits of stability of the Al-Al2Fe abnormal eutectic microstructure have been observed. When the G R ratio is low, Al3Fe grows as frequently branched, narrow platelets in a dendritic aluminium matrix. When G R > 1000°C sec/mm2 branching is largely eliminated and [010]Al3Fe ∥ [100]Al ∥ growth direction. The Al3Fe platelets grow in the [010] direction by a twin plane re-entrant edge mechanism in which grooves between faceting {111} planes are formed between multiple (001) twins. (001) twins were observed at 50-200 Å intervals for all freezing conditions, and (100) twins were also observed at higher values of G R.
