    摘要： In one embodiment method to form a composite part from a metallic composite powder, comprises positioning a metallic composite powder preform in a mold cavity formed by a first susceptor and a second susceptor, heating the mold cavity to a first processing temperature, applying a pressure to the mold cavity, and applying a thermal oscillation cycle to the mold cavity, wherein the thermal oscillation cycle oscillates the temperature of the mold cavity between a first temperature in which the metallic composite powder is in a first phase and a second temperature in which the metallic composite powder is in a second phase, different from the first phase.

    摘要： A single or multilayer smart susceptor for temperature control of part fabrication in an induction processing system generally consists of single layer or laminated layers of ferromagnetic material susceptible to heating by induction. The use of the susceptors in fabrication at elevated temperatures causes oxidation damage to the surface. The susceptor may be coated with a nickel aluminide surface coating to minimize oxidation of the susceptor outer surface.

    摘要： A method and apparatus for forming a workpiece having a desired configuration as well as an associated preform assembly are provided. The forming method and apparatus as well as the preform assembly include a hydrostatic pressing medium, such as a layer of glass, disposed within the die cavity proximate to at least one side of the workpiece. The hydrostatic pressing medium is configured to have a relatively low viscosity at the temperatures at which the workpiece is processed, thereby facilitating the relatively even application of pressure to the workpiece. As such, a workpiece having a complex configuration may be formed utilizing a single acting die.
