ABSTRACT:
A method and apparatus for applying heat sufficient to permit plastic deformation of intermetallic material. The heat is applied to a fractional region of a workpiece, and then manipulations capable of causing the workpiece to deform are applied using conventional sheet metal forming equipment. The invention utilizes elevated forming temperatures to heat the fractional region of the intermetallic workpiece so that the fractional region has sufficient ductility to permit a plastic deformation required for the forming operation. The apparatus is a sheet metal-working machine which has been modified to provide the localized heating required to carry out the process of the present invention.
