Grain refinement of AZ31 magnesium alloy by electromagnetic stirring under effect of grain-refiner
Source abstract
Abstract
The effects of electromagnetic stirring and Al4C3 grain refiner on the grain refinement of semi-continuously cast AZ31 magnesium alloy were discussed in this investigation. The results indicate that electromagnetic stirring has an effective refining effect on the grain size of AZ31 magnesium alloy under the effect of Al4C3 grain refiner. Electromagnetic stirring can ‘activate’ the Al4C3 particles, resulting in more heterogeneous nucleation sites for the primary α-Mg grains. But, longer holding time can ‘deactivate’ the Al4C3 particles and poison the grain refining effect.
