Abstract
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.
