A forging die and process suitable for producing large forgings, including turbine disks and other rotating components of power-generating gas turbine engines, using billets formed by powder metallurgy. The forging die includes a backplate, and segments arranged in a radial pattern about a region on a surface of the backplate. Each segment has a backside facing the backplate and an interface surface facing away from the backplate, with the interface surface being adapted to engage the billet during forging. The segments are physically coupled to the surface of the backplate in a manner that enables radial movement of the segments relative to the backplate.

An improved method and container for forming billets using hot isostatic pressing is provided. The improved method and container have features that control the deformations of the container during the high temperatures and pressures experienced in such processing so as to provide a billet having a predetermined shape such as, for example, substantially parallel, convex, and/or concave sides. Conservations of the powder used for the billet and more efficient use of the container upon the resulting billet can be achieved.

A method for forming an oxide-dispersion strengthened coating on a metal substrate is disclosed. The method generally includes comminuting MCrAlY alloy particles to form an oxygen-enriched powder, wherein at least about 25% by volume of the MCrAlY alloy particles within the oxygen-enriched powder have a particle size of less than about 5 μm. Additionally, the method includes applying the oxygen-enriched powder to the metal substrate to form a coating and heating the oxygen-enriched powder to precipitate oxide dispersoids within the coating.

A formed article comprising a nanostructured ferritic alloy is provided. Advantageously, the article is not formed via extrusion, and thus, cost savings are provided. Methods are also provided for forming the article, and the articles so produced, exhibit sufficient continuous cycle fatigue crack growth resistance and hold time fatigue crack growth resistance to be utilized as turbomachinery components, and in particular, large, hot section components of a gas or steam turbine engines. In other embodiments, a turbomachinery component comprising an NFA is provided, and in some such embodiments, the turbomachinery component may be extruded.

An improved container and method for forming billets using hot isostatic pressing is provided. The method and container allows for adjusting the volume of the container so as to obtain a billet of the desired shape based on selected powder charge for the container. In addition, the corner of the container can be adjusted to allow for elimination of edge effects and further shape control in the resulting billet.
