    Abstract: Apparatus and methods for single sheet forming using induction heating include a pair of dies defining a die cavity for containing a workpiece, which is inductively heated by an oscillating magnetic field within the die cavity. A susceptor is positioned between the workpiece and one die surface defined by one of the dies. The susceptor is capable of coupling with the oscillating magnetic field to induce a current within the susceptor to heat the susceptor. The susceptor transfers heat to the workpiece. An inlet for pressurized forming fluid injects the fluid between the susceptor and the workpiece to form the workpiece into direct contact with a forming surface defined by one of the dies. The susceptor may be electrically connected to the workpiece to inhibit electrical arcing from the susceptor to adjacent electrically conductive components when current is induced in the susceptor. The apparatus may further include a seal frame that releasably engages the workpiece to form a pressurizing cavity between the susceptor and the workpiece. The inlet injects the fluid into the pressurizing cavity to develop and apply forming pressure to the workpiece.

    Abstract: 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.
