Abstract
During vertical Bridgman crystal growth, local solute accumulation along the freezing interface due to buoyancy often causes radial non-uniformity and pit formation, which accelerate morphological instability. A novel approach by using angular vibration has been proposed. Through the visualization of the freezing interface during directional solidification of succinonitrile containing acetone, it was shown that angular vibration about the growth axis was effective in reversing radial segregation and thus enhancing morphological stability. Simulation was conducted and good agreement was found. © 2004 Elsevier B.V. All rights reserved.
