摘要：
The minimized segregation during the controlled directional solidification of dendritic alloys was discussed. It was found that the application of a slow axial rotation during controlled directional solidification of dendritic alloys promoted microstructural homogeneity. The analysis showed that the optimized rotation eliminated channel segregates and only a quiescent microgravity environment ensured diffusion-controlled growth.
