Abstract

The computational heat and mass transfer modeling approach presented in this paper emphasizes the influence of undercoolings on dendrite structure formations of the alpha phase crystals inherent to advanced phases of an aluminum brazing netshape manufacturing sequence. In the first segment of this work, the empirical evidence involving the outcome of the solidification process and its kinetics was presented. In this paper, simulation of the alpha phase crystal pattern formation is corroborated with empirical findings obtained by utilizing an AA4343/AA3003 brazing sheet exposed to controlled atmosphere brazing (CAB) in ultra-high purity nitrogen.
