A forging method including extruding a billet to form a ring shaped hollow workpiece; reducing a cross section of the workpiece; and forging the workpiece in a closed die having a first split die including a plurality of first die segments and a second split die including a plurality of second die segments by sequentially advancing pairs of opposing die segments from the first split die and second split die towards each other.

Near net shape forging process for compressor and turbine wheels and turbine spacer wheels

A method of forging a workpiece includes (a) incrementally advancing the workpiece in a closed die forge, the closed die forge including a stationary, flat die and a first split die including a plurality of first die segments, each die segment being incrementally advanced in sequence to contact the incrementally advancing workpiece; (b) replacing the stationary, flat die with a second split die including a plurality of second die segments; and (c) forging the workpiece forged in (a) between the first split die and the second split die, wherein the first die segments are stationary and at least some of the plurality of second die segments are incrementally advanced in sequence.
