Study on the Structure and Property of Hypoeutectic Al-Si Alloy Under Electromagnetic Fields
The microstructure and properties of hypoeutectic Al-Si alloy under the electromagnetic field have been studied. It is found that under the conditions of the electromagnetic oscillations, the microstructure of hypoeutectic Al-Si alloy was gradually refined. Comparing with the single electromagnetic field under the same conditions, the microstructure has been further refined, and the mechanical properties were significantly increased under the conditions of the electromagnetic field. In the experimental conditions, the microstructure refinement and properties of hypoeutectic Al-Si alloy are best when the current density I=63.69 mA/mm2 and the magnetic intensityB=0.153 T.
