摘要：

The undercooling behaviors of three Al-Cu alloy melts in a steady magnetic field (SMF) were investigated by differential thermal analysis. It was found that the nucleation temperatures of primary phases in three alloys gradually shifted to a lower temperature with increasing the SMF intensity, i.e., the undercooling was enhanced in the SMF. The enhanced undercooling mainly results from the increase in the liquid/solid interfacial free energy in the SMF. In addition, the reduction of migration rates of atoms in the liquid phase in the SMF is partially responsible for the increase in undercooling. Copyright (C) EPLA, 2019
