A system for removing residual powder from a three-dimensional (3D)-printed component integrally constructed with a build plate during an additive manufacturing (AM) process includes an end-effector, an enclosure, one or more transducers, and an electronic control unit (ECU). The end-effector includes a base surrounded by a perimeter flange, and includes a through-opening that receives the build plate. A perimeter clamp attaches and seal the enclosure to a perimeter flange of the end-effector such that the enclosure, the base, and the build plate collectively form a powder containment cavity. The transducers vibrate at a predetermined frequency or range thereof. The ECU transmits a vibration control signal to the transducers during a post-processing stage of the AM process to loosen and remove the residual powder from the component and collect the loosened powder within the powder containment cavity.

A sputtering target containing, as metal components, 0.5 to 45 mol % of Cr and remainder being Co, and containing, as non-metal components, two or more types of oxides including Ti oxide, wherein a structure of the sputtering target is configured from regions where oxides including at least Ti oxide are dispersed in Co (non-Cr-based regions), and a region where oxides other than Ti oxide are dispersed in Cr or Co—Cr (Cr-based region), and the non-Cr-based regions are scattered in the Cr-based region. An object of this invention is to provide a sputtering target for forming a granular film which suppresses the formation of coarse complex oxide grains and generates fewer particles during sputtering.

The invention relates to nano-particles comprising metallic ferromagnetic nanocrystals combined with either amorphous or graphitic carbon in which or on which chemical groups are present that can dissociate in aqueous solutions.

According to the invention there is provided nano-particles comprising metal particles of at least one ferromagnetic metal, which metal particles are at least in part encapsulated by graphitic carbon.

The nano-particles of the invention are prepared by impregnating carbon containing bodies with an aqueous solution of at least one ferromagnetic metal precursor, drying the impregnated bodies, followed by heating the impregnated bodies in an inert and substantially oxygen-free atmosphere, thereby reducing the metal compounds to the corresponding metal or metal alloy.

There is provided conductive paste excellent in electro-conductivity and thermal conductivity. Conductive paste comprising conductive filler being composite particles including copper powder and nanosize precipitates which are disposed on the surface of the copper powder and composed of at least one kind of transition metal belonging to the group 8 to group 10 of the periodic table or a compound of the transition metal, and a binder resin.

A finish heat treatment apparatus for an iron powder. Raw iron powder is placed on a continuous moving hearth and continuously charged into the apparatus. In a pretreatment zone, the raw iron powder is subjected to a pretreatment of heating the raw iron powder in an atmosphere of hydrogen gas and/or inert gas at 450 to 1100° C. In decarburization, deoxidation, and denitrification zones, the pretreated iron powder is subsequently subjected to at least two treatments of decarburization, deoxidation, and denitrification. In the pretreatment zone, a hydrogen gas and/or an inert gas serving as a pretreatment ambient gas is introduced separately from an ambient gas used in the at least two treatments is introduced from the upstream side of the pretreatment zone and released from the downstream side so as to flow in the same direction as a moving direction of the moving hearth.
