ABSTRACT:
A process for forging hollow elongated articles from superalloys and titanium alloys. The process employs preconditioned material which has low strength and high ductility. The process is performed in a forging press and has an initial step which converts a preform into a intermediate shape by press motion which produces radial outward workpiece flow. Press punch geometry is then changed and the operation continues with radial inward flow about a mandrel.
