METHOD OF MANUFACTURING BY COLD FLUOTURNING AN INCONEL 718 ALLOY PART

摘要

The invention relates to a production process by cold spinning, (or by strong hardening) of an alloy piece 718 (Inconel 718), optionally followed by an aging heat treatment. BR/ The process according to the invention In particular, the invention makes it possible to obtain, by cold spinning, bodies or cylindrical structures having very high mechanical characteristics, especially when hot. BR/ Such metal bodies or structures of great length but thin can be used in particular as tanks or as a propellant structure in the aeronautical industry.
