    摘要: A method of moulding superplastic alloy sheet material by holding a blank of sheet material, heated to a temperature at which it exhibits superplasticity, adjacent a fluid pressure duct or manifold, and applying fluid pressure to the blank sheet through the duct or manifold to cause the heated sheet to conform to the shape of a mould surface arranged on the side of the sheet remote from the duct or manifold. The fluid pressure manifold may be a heated plate having a plurality of apertures therein.

    摘要: A process for working superplastic sheet material comprising shaping the superplastic alloy by pressure or vacuum forming, annealing the sheet material before or after the pressure of vacuum forming, and bending at least a part of the shaped sheet at room temperature. In a preferred procedure rolled superplastic zinc/aluminium alloy sheet material is annealed at about 200* C for at least one hour, vacuum or pressure forming carried out at 200* C to 250* C after the annealing, and the shaped sheet allowed to cool to room temperature before bending.
