METHOD FOR THE PRODUCTION OF PARTS BY MEANS OF DIFFUSION BONDING AND SUPERPLASTIC FORMING, AND MOLD FOR CARRYING OUT SAID METHOD

摘要

The invention relates to a method for producing parts (2) comprising at least one internal cavity (4), said method consisting of three successive steps: first, at least two metal sheets (14) are diffusion bonded; then said bonded metal sheets are bent; and third, each of the internal cavities (4) is inflated by means of superplastic forming. The inventive method is carried out by means of a mold (1) allowing at least one first part (2a) to be diffusion bonded and then bent while inflating at least one second part (2b) by means of superplastic forming during a single operation, whereby said mold is heated. The inventive method applies to the field of aeronautics.
