Abstract
An elastically deformable die includes two or more die members formed of materials exhibiting different degrees of elastic deformation under the same stress which are combined and arranged such that the elastic deformation thereof under the pressure received from a workpiece during a forming operation causes the surface of the die in contact with the workpiece to be formed to a prescribed configuration. In die forming the composite die is brought in contact with a surface of the workpiece, the die is elastically deformed at the surface of contact by the pressure received from the workpiece during the forming process, and the workpiece is formed to the prescribed configuration by this deformation.
