Abstract

Ag-15wt%Cu hypoeutectic and Ag-28.1wt%Cu eutectic alloys were solidified in a containerless environment using a 3m drop tube. It is found that for Ag-15wt%Cu hypoeutectic alloy, with the decreasing of the droplet size, a "dendritic-equiaxed" morphology transition takes place. Meanwhile, for Ag-28.1wt%Cu eutectic alloy, a "regular lamellar eutectic-irregular anomalous eutectic" microstructure change occurs. The dendrite fragmentation mechanism and TMK model of eutectic growth were used to analyze the experimental results.
