METHOD FOR PRODUCING A CORRUGATED FOIL BEARING STIFFENER AND OBTAINED STIFFENER

摘要

The invention concerns a method for producing a corrugated foil bearing stiffener which involves starting with an austenitic nickel superalloy sheet (15) having an elasticity limit higher than 500 MPa, and subjecting the sheet (15) to at least one step of press bending plastic deformation of the entire thickness of same with a deformation energy higher than 10 kJ in a time shorter than 10-5 s in such a way as to create corrugations.
