Abstract
A method is disclosed for heating a cold worked sheet of superplastically formable metal composition to recrystallize its microstructure to a formable condition and/or to heat the sheet to a temperature for an immediate forming operation. The sheet is placed between two electrical resistance heated platens maintained at a suitable temperature for recrystallizing and/or heating the metal sheet through its side surfaces. In a preferred embodiment a critical gap is maintained between the platens and the sheet to permit rapid conductive heating of the expanding sheet without marring its surfaces.
