Abstract

Graphical abstract: Highlights: The magnetic field disperses grain boundary segregation. By the 3D-CT reconstruction, the flow distribution is seen. This work clarifies ambiguous understanding on the effect of the magnetic field on segregation. Abstract: As concentration distribution changes have important effects on material structures and properties, controlling the concentration distribution is essential to alloy performance. The aim of the present work is to control and adjust the concentration distribution by the static magnetic field. It is found that the magnetic field disperses grain boundary segregation and causes the uniform distribution of concentration. Further, by the three-dimensional computed tomography (3D-CT) reconstruction, the flow distribution is seen and the effect mechanism of the magnetic field is revealed. The present work may clarify the ambiguous understanding on the effect of the static magnetic field on solidification process.
