Effect of static magnetic fields on the recalescence behavior of undercooled Co-Sn liquid

摘要：

　　The recalescence behavior of undercooled Co-Sn alloys under static magnetic fields was investigated using glass slag fluxing technique in a 12T superconducting magnet.Results indicated that the nucleation temperature and the highest temperature after recalescence of undercooled melt can be affected by the static magnetic field.The undercooling for Co-Sn alloys keep unchanged when a strong magnetic field was applied while the recalescence extent was reduced.With the increasing Co content for Co-Sn eutectic systems,the effect of the magnetic field on the recalescence was strengthened.We find that the magnetic field has very limited effect on the nucleation temperature on alloys while the highest temperature after recalescence is affected by the field depending on the magnetization difference of the undercooled melt before and after solidification.
