METHOD FOR MANUFACTURING SOLDERED LEVEL BEARING STIFF STIFFENER AND STIFFENER OBTAINED

摘要

The invention relates to a method for producing a corrugated sheet-bearing stiffener in which a nickel-based austenitic superalloy sheet (15) having a yield strength of greater than 500 MPa is used, and the sheet metal (15) to at least one step of plastic deformation in flexing by deep drawing throughout its thickness with a deformation energy greater than 10 kJ in a time less than 10-5 s so as to create corrugations.
