To provide a manufacturing method for a casting having the fine unidirectional tesseral structure.
The horizontal continuous inverted oscillation for repeating normal/reverse rotation, wherein while gradually moving upward a solidification interface so that the temperature gradient of a molten metal in the solidification interface becomes 1-less than 20°C/cm by cooling the molten metal filled in a casting mold directing from the lower part to the upper part, at the same time, the normal rotational whose maximum angular acceleration is 5 πrad/sec2 or more, and the rotation angle is 5-less than 45° is applied to the casting mold filled with the molten metal, then in succession, the reverse rotation of the same condition is applied, or the horizontal intermittent normal oscillation, wherein the rotation whose maximum angular acceleration is 5 πrad/sec2 or more, and the rotation angle is 5-less than 45° is applied, then stopped, and in succession, the rotation for rotating with the same condition and in the same direction are repeated, is imparted.
