Method for producing a long alloy billet

PROBLEM TO BE SOLVED: To provide a method for producing a long-length alloy billet having uniform density. SOLUTION: The method for producing a long-length alloy billet comprises: a step where a first alloy billet (1), a second alloy billet (1) and alloy powder (2) are prepared; a step where the first alloy billet (1), the alloy powder (2) and the second alloy billet (1) are stacked in a mold (3) in order from below; and a step where a stacked body in the mold (3) is press-compressed in such a manner that the alloy powder grains are bitten into the first alloy billet and the second alloy billet to be integrated, thus one long-length alloy billet (4) is produced.
