Description: Using this alloy composition, a relatively low volume fraction of pro-eutectic dendrites are formed. The eutectic material between these dendrites can be etched away to reveal the three-dimensional structure of dendrites. The dendrite tips are a volume of revolution, and anisotropy develops behind them with the secondary dendrite arms.
