A process for producing a W—Ni sputtering target includes providing the sputtering target with 45 to 75 wt % W and a remainder of Ni and common impurities. The sputtering target contains a Ni(W) phase, a W phase and no or less than 10% by area on average of intermetallic phases measured at a target material cross section.

A metallic material manufactured by a method including steps of (1) subjecting a semifinished metallic billet having at least one of a nanocrystalline microstructure and an ultrafine-grained microstructure to a rotary incremental forming process to form an intermediate wrought metallic billet and (2) subjecting the intermediate wrought metallic billet to a high rate forming process, wherein the high rate forming process includes a high rate forming process average equivalent strain rate, the high rate forming process average equivalent strain rate being at least about 0.1 s−1.

A method can include processing material via at least one severe plastic deformation process to form a degradable component where the material includes aluminum and one or more metals selected from a group of alkali metals, alkaline earth metals, group 12 transition metals, and basic metals having an atomic number equal to or greater than 31.

A method for simply producing components suitable for use under high loads and risks of wear and which have a core portion which consists of a metal material and a wear-resistant layer on a peripheral surface of the core portion is disclosed. A core portion blank is provided and consists of the metal material whose dimension in a first spatial direction is greater than the desired finished dimension of the core and whose second dimension is smaller than the desired finished dimension is provided. A material that forms a wear-resistant layer in the component is applied to a peripheral surface of the core portion blank. The composite body is shaped to form the component. The component may then be optionally finished.

A method of carburizing a powder metal part involving more than one carburizing step. In a pre-forging carburizing step, a powder metal part that is less than fully dense is carburized to establish a pre-forging carburization profile. After the pre-forging carburizing step, the powder metal part is forged so that the powder metal part is increased in density and the pre-forging carburization profile is transformed into an as-forged carburization profile. In a post-forging carburizing step following the forging step, the powder metal part is again carburized, thereby resulting in both further diffusion of carbon from the as-forged carburization profile into the powder metal part and further introduction of carbon into the powder metal part at a surface of the powder metal part.
