Abstract
The dendritic microstructure of an unidirectionally solidified Al-4.4 wt% Cu alloy has been characterised by automatic image analysis. A geometric model has been developed to describe this microstmcture. Eutectic was formed between the primary and secondary dendrite arms at the end of solidification independing on the conditions of solidification. The eutectic covered 10-12% ofthe dendrite surface.
