Notes:
The distribution and solidified structure of alloying elements are important for thequality and the properties of alloys. In the present study, the solidification behavior ofaluminum-rich alloys is studied under various high magnetic field conditions, and theinfluences of uniform and gradient magnetic fields with different intensity and direction on thedistribution and the morphology of solute elements of Al-Cu and Al-Mg alloys are investigated.It is found that because of the differences of the electromagnetic force (Lorentz andmagnetization forces) acting on Cu element and Mg element with different physical propertiesin the matrix, the regularities of distribution for Cu element and Mg element are opposite just inthe intracrystalline and intergranular under high uniform magnetic field condition, and not onlythe content but the distributions of Cu and Mg elements are obviously different under highgradient magnetic field conditions as well. It can be concluded that high magnetic field hasdifferent effect on the solute distribution in alloys with different physical properties such asdensity, susceptibility, conductivity, etc. And the experimental results indicate that it is possibleto control the terminal solubility and morphology of the solute elements in alloys by highmagnetic fields
