摘要:This study aims to understand the grain refinement behavior of commercial purity Al under the influences of inoculation and rotating magnetic field (RMF). Effects of RMF with magnetic flux density of 6mT on the refinement potency of Al-5Ti-1B were investigated. The experimental results indicate fading effect is obvious after adding 0.2 wt.% Al-5Ti-1B into Al with the holding time of 20 min. However, the fading effect can be eliminated to a great extent when RMF was applied to the inoculated Al until the temperature decreased to 662 C. Meanwhile, the grain size can be further reduced. Compared to the grain size of pure Al under RMF until the temperature decreased to 662 C, the grain size is coarser when applying RMF to the inoculated Al until solidification, which can be ascribed to the Joule heat produced by RMF. ?
