Abstract

Mechanical mold vibration using an electromagnetic shaker has been applied to the gravity die lasting of AA356. The effect of mold vibration on the solidification process is being studied trough analysis of temperature gradients in the mold. The AA356 is heated to 850 °C and then poured in a steel die. The die is then vibrated at different combinations of frequency and amplitude. It is shown that the mold vibration alters the temperature profiles within the mold which is expected to have a significant effect on the microstructure and properties of the casting. Preliminary microstructural results show that mold vibration produces a more uniform dendritic structure and reduces the porosity level.
