Formation mechanism of axial macrosegregation of primary phases induced by a static magnetic field during directional solidification

Understanding the macrosegregation formed by applying magnetic fields is of high commercial importance. This work investigates how static magnetic fields control the solute and primary phase distributions in four directionally solidified alloys (i.e., Al-Cu, Al-Si, Al-Ni and Zn-Cu alloys). Experimental results demonstrate that significant axial macrosegregation of the solute and primary phases (i.e., Al 2 Cu, Si, Al 3 Ni and Zn 5 Cu phases)...
