摘要
Provided are: a method for manufacturing a Ni-based heat-resistant superalloy wire having excellent bending workability; and a Ni-based heat-resistant superalloy wire. The method for manufacturing a Ni-based heat-resistant superalloy wire comprises a rod preparation step for preparing a Ni-based heat-resistant superalloy rod; and a rod processing step in which plastic working having a working rate of 40% or less is repeated several times toward the axis from the circumferential surface of the rod at a temperature of 500° C. or lower until the cumulative working rate reaches 60% or more to reduce the cross-sectional area of the rod. A Ni-based heat-resistant superalloy wire obtained by the manufacturing method has a plastic worked or recrystallized microstructure.
