Abstract
To provide a method for manufacturing a tapered material, which can impart a tapered shape without any molding defect when a ring material made of Ni-based superalloy is subjected to a nosing process. In a nosing process to obtain a tapered materialby covering and pressing an entire circumference of an end portion of a ring materialR made of Ni-based superalloy with a tapered portionof an inner surface of a nosing dieto deform a portion of the circumferential surface of the ring materialR into a tapered shape along the tapered inner surface portionof the die, a nosing process initial temperature Tn (° C.) of another portionof the circumferential surface of the ring materialR where the nosing process is not applied satisfies a relationship of following Formula 1 with a solvus temperature Ts (° C.) of a precipitation phase of the Ni-based superalloy:
