Abstract
A coordinated theoretical and experimental study of the temperature distributions inside a customized vertical Bridgman system for growing β-NiAl crystal has been conducted. This model accounts for the combined effects of phase change dynamics, coupled heat transfer processes of conduction, convection and radiation, variable material properties,and complex geometry pertaining to the system. Comparisons between numerical predictions and experimental measurements show satisfactory agreement. Important processing parameters such as interface curvatures and temperature gradients across the interface, along with possibilities of improving the solidification process have been explored.
