Abstract: There are provided an apparatus and an associated method for manufacturing superplastically formed structural assemblies from preforms. The apparatus includes first and second co-operable dies structured to define a die cavity therebetween for at least partially receiving the preform, at least one heater in thermal communication with the die cavity for heating the preform to a forming temperature, and at least one injector in fluid communication with the die cavity. The injector is structured for injecting pressurized gas into the die cavity to urge the preform against one of the dies to form the preform into the structural assembly. Further, at least one of the injectors is structured for injecting a quenchant into the die cavity to thereby heat treat the structural assembly while distortion of the structural assembly is being at least partially restrained by at least one of the dies.

Abstract: An apparatus and method for consolidating a composite workpiece are provided. The apparatus includes an electromagnetic field generator for inducing a current and thereby heating a susceptor in thermal communication with the workpiece. The workpiece is supported by one or more support tools, each of which transmits the electromagnetic field so that the support tools are not substantially heated by the electromagnetic field. Thus, the time and energy required for heating the workpiece are reduced relative to conventional consolidation techniques.

Abstract: A structural assembly and an associated system and method for manufacture are provided. The structural assembly includes an elongate member and a first connector member that is connected to an end of the elongate member by a braze joint. A second connector member can be connected to an end of the elongate member opposite the first connector by another braze joint. The elongate member is formed of a metal matrix composite material that includes a plurality of fibers of a reinforcement material disposed in a metal matrix. Each connector member is formed of a material that is dissimilar to the material of the elongate member. The braze joints can be formed by selectively heating the braze material, e.g., with an inductive coil that extends circumferentially around only a portion of the structural assembly.
