The controlled tensile deformation of a solid crystalline material, such as metal or ceramic, at elevated temperature, to form shape. For superplastic forming to take place, materials must have a fine grain structure and the ability to maintain this grain structure at higher temperatures. During forming, a superplastic sheet is subjected to gas pressure, to form a shape using a die.
