Abstract:
1. An apparatus for forming a workpiece having a desired configuration, the apparatus comprising: first and second co-operable dies; a susceptor comprised of a conductive material, wherein the first and second co-operable dies and the susceptor are configured to define a die cavity for receiving the workpiece, wherein the die cavity defines the desired configuration of the workpiece, and wherein the susceptor is in thermal communication with the die cavity to repeatedly cycle the workpiece between a first temperature above a beta transus temperature of the workpiece and a second temperature below the beta transus temperature of the workpiece; and a hydrostatic pressing medium disposed within the die cavity so as to be proximate at least one side of the workpiece, the hydrostatic pressing medium configured to be a liquid having a viscosity greater than 10
