Abstract
The effect of vibration (50 Hz) on the formation of aluminum castings of 99.5% purity at various cooling rates was studied. It was found that the presence of vibration leads to an increase in the cooling rate of the castings. It was found that the higher the speed without vibration, the stronger the effect of increasing the speed when vibration was applied. Apparently, this effect is associated with additional mixing of the melt by free-floating crystals.
