Abstract Scope |
Phase evolution during the solidification process is critical to final property performance. Applying an electric current during solidification introduces a perturbation to the dynamics of metal alloy solidification. This introduction of the electric current can disrupt the typical phase formation pathways, leading to unexpected morphological changes or the inhibition of the formation of particular phases altogether. These effects are demonstrated with multiple Al-based systems (Al-Ti, Al-Cu, Al-Fe, Al-Si) as well as with metal matrix nanocomposite systems where the dynamics of phase formation is particularly critical in achieving homogeneous reinforcement distribution. As-solidified materials are characterized by synchrotron-based full-field x-ray imaging to quantify the changes in phase morphology in three dimensions. This research further elucidates the effects of electric current and highlights its potential for industrial application. |
