    摘要： Apparatus and method for superplastic forming. The workpiece is held between a pair of dies that are electrically and thermally nonconductive, and is heated inductively by a coil embedded within the dies. The dies are formed of a material that is substantially transparent to inductive heating. A plurality of electrical conductors are embedded within the die. The electrical conductors are interconnected into one or more electrically conductive coils that surround the workpiece. The electrical conductors are used to produce a time varying magnetic field that is used to heat the workpiece. In one embodiment, the workpiece is a composite material that is susceptible to inductive heating. The composite material includes an electrically conductive material. The time varying magnetic field heats the electrical conductive material, thereby heating the workpiece. The die also includes a forming surface having a shape corresponding to a desired shape of the workpiece. A pressure differential is created between the first and second sides of the workpiece to deform the workpiece to the shape of the forming surface.

    摘要： An apparatus and method for heat treating a structural member, for example, to relieve stresses therein, are provided. The structural member is restrained in a die cavity by one or more inflatable bladders so that a desired dimensional accuracy is achieved. The structural member can be heated by an electromagnetic field generator, such as an induction coil, that heats one or more susceptors to a characteristic Curie temperature. The apparatus can be used to process structural members of various sizes and shapes, and the heating and cooling cycle can be performed relatively quickly.
