Based on the simulation results, directional solidification experiments under traveling magnetic field were performed to obtain thin samples with 7 mm diameter. The experimental results demonstrate that banding is overgrown by peritectic coupled growth or island banding structures as solidification proceeds. Numerical results indicate that this phenomenon should be attributed to the different solute distribution at the S/L interface with different TMF. The effects show that it is possible to control solidification microstructure evolution by using a traveling magnetic field during directional solidification of peritectic alloys.
