PROBLEM TO BE SOLVED: To provide a functionally gradient material in composite materials, in which the volume fraction of fine precipitate particles or GP zones diagonally varies in every position. SOLUTION: The method for manufacturing the functionally gradient material, in which the volume fraction of fine precipitate particles or the GP zones diagonally varies in every position, comprises dissolving an A-B alloy, forming a concentration gradient in a range of equal to or less than the maximum dissolving quantity of the B element into the A element, by applying a centrifugal force on it during melting, and using heat treatment together.
