| Abstract: | Based on the data obtained in our experiment,it was found that the refining effect of pulsed magnetic field on the solidified structure in LY12 Alalloy was better than that of pulsed electric current.Differences of solidified structure and refining mechanisms,working principles and characteristics were compared of the two novel methods for refining solidified structure in LY12 Alalloy between pulsed magnetic field and pulsed electric current.The application prospects were also pointed out. |
