In-situ analyzing the Influence of Thermoelectromagnetic Convection on the Nucleation ahead of the Advancing Interface during Directional Solidification

摘要：

　　Sn-3wt%Pb alloy was directionally solidified without and with a 0.08T transverse magnetic field(TMF),and real-time recorded by in-situ synchrotron X-ray imaging.Results indicate that TMF shortened the distance from the location of nucleation to the advancing interface,and accelerated the growth rate of the equiaxed crystal,which caused the columnar-to-equiaxed transition(CET)finally.The thermoelectromagnetic convection(TEMC)in front of the interface and around the crystals dendritic branch should respond to changes of the distance and the growth rate.
