To fully understand the microstructure transition during solidification of metal alloys, a 3-D phase field model was developed. An algorithm, namely Para-AMR, comprising of adaptive mesh refinement (AMR) and parallel (Para-) computing capabilities was developed to solve the phase field equations. Results showed that employment of this approach could speed up computational efficiency for about 3 orders magnitude. Synchrotron X-ray image techniques were also applied in this study to (1) reveal the full physics of the solidification phenomena in real space and time scales, and (2) to fully testify the validity of the phase field modeling results. Accordingly, solidification behaviors, including dendrite growth and pattern formation (for both fcc and hcp dendrites), fragmentation (under the influence from electromagnetic forces and ultrasounds), and coarsening were studied and compared with either experiment results or existing theories.
