Effect of a High Static Magnetic Field on the Origin of Stray Grains during Directional Solidification

The formation of stray grains in directionally solidified Al-4.5 mass% Cu alloy under an axial high static magnetic field up to 6 T has been investigated. Electron backscattering diffraction (EBSD) was performed to analysis the orientation of the stray grains. The experimental results suggest that the formation of the stray grains are significantly affected by the external magnetic field. The modification of dendrite morphology demonstrates the...
