Effect of mechanical vibration during the solidification process of an aluminium alloy A356

The treatment with mechanical vibrations during the solidification process promote microstructural changes in metallic alloys, in order to have a better understanding on this matter mechanical vibration were applied to an aluminum alloy A356, while teeming in order to evaluate the morphological changes on ?Al primary phase in the solidification process. Two routes were analyzed, a cooling slope and a rotational mold. This paper shows the results of quantify the effect of mechanical vibration and the specific characteristic of casting to obtain a spherical morphology on the ?Al primary, that allow to obtain thixoformable raw material.
