Description
By using of Al-20wt%Cu alloy, solidification experiments were performed by unidirectional solidification in our Bridgman-type furnace. A constant temperature gradient (~6 K/mm) and two different solid/liquid interface velocities (from 0,02 to 0,2 mm/s) was used. The sample movement velocity was suddenly increased during the solidification process.
The aim of our experiments was to investigate the effect of the rapid increase of sample movement velocity on the microstructure of the samples. Moreover, the effect of solid/liquid interface velocity and the effect of the use of grain refining material on the microstructure and grain structure of solidified samples were also investigated.
