Description
Summary:The effects of Al-Al 4 C 3 grain refiner and electromagnetic stirring on the grain refinement of AZ31 magnesium alloy were studied in this investigation. The results indicate that electromagnetic stirring can effectively refine the crystal size of AZ31 alloy with the presence of Al-Al 4 C 3 grain refiner. Under the effect of electromagnetic stirring, Al-Al 4 C 3 refiner has outstanding refinement of the structure of AZ31 alloy due to the activation effect of low frequency electromagnetic field to Al-Al 4 C 3 particles.
