  • Installation for shaping a hollow blade
    Publication number: 20060005594
    Abstract: A hollow blade is shaped by superplastic inflation of a blank made up of welded-together sheets. A die comprising two hollow shapes clamping the outline of the blank is placed inside an autoclave-forming enclosure in order to subject the blank to superplastic inflation, and the two hollow shapes are united by U-shaped clamps made of a material having a coefficient of thermal expansion that is smaller than that of the material constituting said shapes.

  • Method of manufacturing sheets made of alloy 718 for the superplastic forming of parts therefrom
    Patent number: 6328827
    Abstract: In order to obtain sheets made of a nickel-based superalloy of type 718 having properties of superplasticity, the sheets are manufactured with a final cycle comprising the steps of: a) solution treatment at 1060° C. for 15 minutes; b) precipitation at 730° C. to 800° C. for 1 to 2 hours; c) cold rolling at a ratio greater than 60%, and d) recrystallization at 900° C. for 30 minutes. Superplastic deformation of such sheets is carried out at about 970±10° C. and under pressures inducing stresses between 45 and 60 MPa.
