Effects wave parameters of the accelerated crucible rotation technique (ACRT) on the solid-liquid interface concavity and the solute segregation were investigated. The results show that for the four kinds of wave parameters, the ACRT results in an uniform solute concentration field in the melt in the front of the solid-liquid interface. However, ACRT wave parameter has crucial effects on both the solid-liquid interface shape and the solute segregation in the crystal. With a suitable wave parameter, the ACRT can make the solid-liquid interface concavity increase a little, or even not increase, and decrease the radial solute segregation in the single crystal extraordinarily, even to be equal to zero. On the contrary, with an unsuitable wave parameter the ACRT can make the solid-liquid interface concavity increase in a great deal, even up to six times, and increase the radial solute segregation significantly. Moreover, the ACRT increases the axial solute segregation apparently with all the four kinds of wave parameters mentioned in this paper.
