In this work, ultrasound has been employed to help prepare Al-Sc alloys using the molten salt electrolysis. The effects of synergetic ultrasound on the Sc content and primary Al₃Sc particles of Al-Sc alloys are specifically investigated. Ultrasound can strongly promote the Sc content of the electrolytic Al-Sc alloy and transform the large Al₃Sc phase clusters into fine cubic particles. Meanwhile, it also homogenizes the distribution of Al₃Sc phase. The Sc content increases by 74.4 % up to 1.43 wt.% when applying ultrasound during both electrolysis and solidification process. It also transforms the molten salts/liquid Al interface by enhancing the wettability. The huge primary Al₃Sc phase clusters transform into fine cubic particles by ultrasound. The average particle size reduces from 77 ± 36 μm down to 21 ± 8 μm. The concerned mechanism have been discussed in detail.

在这项工作中，已采用超声波帮助使用熔融盐电解制备Al-Sc合金。特别研究了协同超声对Al-Sc合金中Sc含量和Al ₃ Sc初生颗粒的影响。超声波可以大大提高电解Al-Sc合金的Sc含量，并将较大的Al ₃ Sc相簇转变为精细的立方颗粒。同时，还使Al ₃ Sc相的分布均匀。在电解和凝固过程中施加超声波时，Sc含量增加74.4％，最高达到1.43％（重量）。它还通过提高润湿性来转变熔融盐/铝液的界面。巨大的原始Al ₃Sc相簇通过超声转变成细小的立方颗粒。平均粒径从77±36μm降低到21±8μm。已经详细讨论了有关机制。
