On Nucleation Temperature of Pure Aluminum in Magnetic Fields

Progress In Electromagnetics Research Letters, Vol. 15, 45-52, 2010


Solidification of pure aluminum without and with a magnetic field has been investigated by differential thermal analysis (DTA). DTA curves showed that the nucleation temperature of pure aluminum was decreased as a magnetic field strength increased although its melting process was almost not influenced. The nucleation suppression could be attributed to the increase of the solid-liquid interfacial energy which might originate from more orderly arrangement of atoms on the solid-liquid interface upon applying a magnetic field.
