A Manufacturing method for profiled ring of Ni-base superalloy for obtaining a uniform microstructure |
摘要 |
PURPOSE: A manufacturing method of a nickel-based superalloy profile ring having uniform microstructure is provided to form uniform structure by forming thermal process under a specific temperature condition after a ring rolling. CONSTITUTION: A manufacturing method of a nickel-based superalloy profile ring having uniform microstructure is as follows. The billet consisting of the nickel base super alloy is prepared. A billet is heated in a constant temperature range. The heated billet is compacted. A center portion of the billet is punched in order to form a hollow billet. The hollow billet is ring rolled and forms a shape ring. The shape ring is heat-treated in order to make uniform organization. |
