摘要： PROBLEM TO BE SOLVED: To smoothly perform upset forging by suppressing an elongation amount caused by reduction by an anvil without impairing the efficiency of reduction by the anvil.SOLUTION: When the reduction of a forming blank 4 is carried out and an elongation amount L1 of the forming blank 4 after the reduction is large and the elongation amount L1 is out of a halfway specified range, the anvil 3 is rotated and the reduction by the anvil 3 is started, and reduction by the rotation of the anvil 3 is continued until the completion of upset forging. When the elongation amount L1 is within the halfway specified range, the reduction speed is changed, and the reduction of the forging blank 4 is carried out without rotating the anvil 3.

CONSTITUTION: A core mold 1 having an outer shape almost equal to the shape of a molding passage and subjected to release treatment is arranged in upper and lower materials 2, 3 to form a capsule 4 and a lining powder good in corrosion resistance and abrasion resistance is charged in the gap between the outer surface of the core mold 1 in the capsule 4 and the inner surfaces of the upper and lower materials 2, 3 to be degassed and hermetically sealed and subsequently subjected to hot isotropic pressure treatment to bond the lining powder 17 to the inner surface of the upper lower materials by diffusion bonding to mold a sheet. The material quality of the upper and lower materials 2, 3 is set to a two-phase alloy and, after the completion of diffusion bonding, heat treatment adjusting the amt. of an alloy phase is applied.
