  • Advanced forming techniques for superplastic forming
    Patent number: 5862695
    Abstract: This invention defines an improved method for superplastic forming (SPF) of metallic parts in which a cutout is formed in the blank from which the parts will be formed, and a secondary sheet is located between the blank and the pressurized gas. The cutout area of the blank becomes stretched so that there is minimal thinning in the air near the periphery of the cutout(s) in the blank, the secondary sheet is required to carry the gas pressure and to form the parts.
