Study on Dendrite Growth Process of Cubic System Alloy Based on Mathematical Models

An improved MCA model was established and the dendrite growth process of NH4Cl-H2O transparent alloy was simulated, including single equiaxed crystal, multi-equiaxed crystal with different preferential growth orientation, and the columnar dendrites whose preferential growth orientation is not parallel to the x-axis. The simulation results were compared with the experimental results. The results show that the MCA model can accurately simulate the dendrite growth process with different preferred growth orientation.
