Provided is an oxide-containing magnetic material sputtering target wherein the oxides have an average grain diameter of 400 nm or less. Also provided is a method of producing an oxide-containing magnetic material sputtering target. The method involves depositing a magnetic material on a substrate by the PVD or CVD method, then removing the substrate from the deposited magnetic material, pulverizing the material to obtain a raw material for the target, and further sintering the raw material. An object is to provide a magnetic material target, in particular, a nonmagnetic grain-dispersed ferromagnetic sputtering target capable of suppressing discharge abnormalities of oxides that are the cause of particle generation during sputtering.

A method of metallurgical processing includes, providing a workpiece that has been formed by additive manufacturing of a nickel-chromium based superalloy. The workpiece has an internal porosity and a microstructure with a columnar grain structure and delta phase. The workpiece is then hot isostatically pressed to reduce the internal porosity and to at least partially retain the columnar grain structure and the delta phase. The workpiece is then heat treated to at least partially retain the columnar grain structure and the delta phase.

The present invention may comprise processes, methods, and systems for powder processing aimed at and characterized in reduction of adsorbed gases, vapors, particulates, and moisture through high-temperature vacuum out-gassing by disintegrating the powder bulk or flow into separate particles. Heat may be transferred to powder particles in vacuum by multiple interactions during intimate contact with heated metal balls within a tube or other container.

A furnace isolation chamber for containing a component to be Hot Isostatically Pressed is disclosed. The disclosed furnace includes inherent passive features to assist in the containment of released toxic gases via a thermal gradient within the chamber. The chamber comprises longitudinally cylindrical sidewalls; a top end extending between and permanently connected to the sidewalls, thereby closing one end of the chamber; and a movable bottom end, which is opposite the top end and forms a base end of the chamber. The movable bottom end is adapted to receive the component, and comprises a mechanism for raising and lowering the component into the high temperature zone of the furnace in the HIP system. The isolation chamber forms an integral part of the HIP system with the base end of the chamber comprising a cool zone as a result of being located outside of the high temperature zone of the furnace.
