It is shown that high intensity ultrasonic wave can raise the nucleation rate of the liquid and can restrain the growth of Si; cavitation effect can break Si crystal in growth,change its shape and distribution, and decrease its weakening effect on the matrix; ultrasonic modification is an effective means of fining the structure and improving the properties.
