摘要： A forging press includes a die set having a stationary die, a movable die in facing-but-spaced-apart relation to the stationary die along a press axis and defining a workpiece volume therebetween, and an exterior constraint extending circumferentially around the workpiece volume. The movable die has a base level region lying generally in a workpiece plane perpendicular to the press axis, and three rotationally symmetric segments raised above the base level region. Each of the segments forms an angular segment of a disk having an included segment angle and that is angularly separated from the other segments. A press mechanism includes a axial drive operable to move the movable die in a direction parallel to the press axis, and an indexing drive operable to rotate the movable die about the press axis by an indexing rotational angle. In operation, the axial drive performs a press stroke and retracts, the indexing drive rotates the movable die by the indexing rotational angle of less than the included segment angle, and the axial drive performs another press stroke. By repeating these steps, the entire workpiece is forged incrementally.

摘要： An article is formed from an ingot of a nickel-iron base alloy having a composition including from about 4.5 weight percent niobium to about 5.5 weight percent niobium and capable of forming delta-phase precipitates, and having fewer than about 1 grain per square inch at 100× magnification. An array of intragranular delta-phase precipitates is precipitated within the ingot to provide grain nucleation sites. The ingot having the array of delta-phase precipitates therein is deformed at a temperature below a delta-phase solvus temperature, thereby producing a fine-grained billet.
