Control of Alloying Element Segregation and Precipitated Phase Distribution in the Solidified Structures of Alloy Using High Magnetic Fields
The effects of high magnetic fields on the segregation of alloying elements and the distribution of precipitated phases in the solidified structure of Mn-89.7wt.％ Sb alloy have been investigated. It was found that the application of a uniform magnetic field promoted the homogeneous distribution of MnSb particles in the alloy and weaker gradient magnetic fields caused the segregation of MnSb particles. Under steeper gradient field conditions, the dendrites of both of two primary phases, i. e. MnSb and Sb of the alloy were found to coexist in MnSb/Sb eutectic matrix and gather in certain regions. The above phenomena may be attributed to the performance of Lorentz force and magnetic force. The results suggest that high magnetic fields may potentially be tailored to control the segregation of alloying elements and distribution of precipitated phases during solidification process directly.
