中文摘要：

liquidus 温度附近的一个电磁的激动人心的过程被设计并且试验性地示威了生产 AZ91 镁合金的半固体泥浆，以便避免污染从不仅机械激动人心而且 Mg 合金的发炎在提高的温度融化。AZ91 合金化工物品是等温地，热为 20 min 在 600-610 对待，然后由电磁的地搅动了。球状的主要粒子特征在铸造物光学地被观察。机械性质也被学习。

英文摘要：

An electromagnetic stirring process near liquidus temperature was designed and demonstrated experimentally to produce semi-solid slurry of AZ91 magnesium alloy, in order to avoid not only contamination from mechanical stirring but also the inflammation of Mg alloy melt at elevated temperature. AZ91 alloy feedstock was isothermally heat treated at 600-610℃ for 20 min, and then stirred by electromagnetic field. Globular primary particle characteristic was observed optically in the castings. Mechanical properties were also studied.
