An exemplary process includes determining a desired pore size, selecting an initial pore size greater than the target pore size, manufacturing a porous structure with the initial pore size, forging the porous structure to form a forged part having the desired pore size, and forming an orthopedic device from the forged part.

The invention relates to a method for manufacturing a laminated or forged material, the thickness of which is 14 to 100 mm. The materials according to the invention are particularly suitable for manufacturing airplane underwing elements.

A sprocket wheel, which is a machine component configured to slide relative to a bushing while being in contact with the bushing in an outer peripheral surface, includes a base made of a first metal, and an overlay that covers the base so as to constitute the outer peripheral surface. The surface of the overlay constituting the outer peripheral surface has been smoothed. Such a smoothed surface of the overlay makes the sprocket wheel less damaging to the bushing.

Austempered steel for components requiring high strength and high ductility and/or fracture toughness, which has a silicon content of 3.1 weight-% to 4.4 weight-% and a carbon content of 0.4 weight-% to 0.6 weight-%. The microstructure of the austempered steel is ausferritic or superbainitic.

Provided are discs and bores of a gas turbine engine having one or more graphene layers and methods of preparing the same. The one or more graphene layers are disposed adjacent to the disc rim and/or bore to improve heat transfer and reduce oxidation of the discs. Methods of preparing the graphene layers and systems for using the same are provided.

The disclosure is directed to an apparatus comprising feedback-assisted control of the heating process in rapid discharge heating and forming of metallic glass articles.

A forging method is provided. The forging comprises determining plans of second and third processes for each of a plurality of ingots, categorizing the plurality of ingots into first and second ingot sets, based on the plans of the second and third processes, evaluating the first and second ingot sets using a scoring function, determining an ingot set to be provided to a first heating furnace, based on the evaluating of the first and second ingot sets, and performing a first process, different from the second and third processes, on the ingot set provided to the first heating furnace.

The post forging solution anneal step normally carried out on hot forgings made from highly alloyed metals can be eliminated while still avoiding the formation of deleterious intermetallic phases by adopting a number separate features in connection the way the forging is made.

The invention discloses a process of manufacturing heavy and critical components such as a blowout preventer (BOP) with a combination of open die forging, piercing and machining process which results in to better material utilization and saving in the machining time. The forging process of the invention involves a step of notching, wherein a transverse notch is made near each end of the ingot before cogging said ingot. The invention allows development of safety and critical components with effective material utilisation.
