Abstract: A three-dimensional PBF-AM apparatus includes a stage on which a powder material is spread, and a tubular build box disposed in a state of surrounding the stage. The build box includes a side wall portion having a first tubular member surrounding the stage and a second tubular member surrounding the stage with the first tubular member interposed therebetween and forming a space with the first tubular member, and moreover, a vacuum heat insulating layer can be formed inside the side wall portion by vacuuming the space.

Abstract: A method, product, apparatus, and article of manufacture for the application of the Composite Based Additive Manufacturing (CBAM) method to produce objects in metal, and in metal fiber hybrids or composites. The approach has many advantages, including the ability to produce more complex geometries than conventional methods such as milling and casting, improved material properties, higher production rates and the elimination of complex fixturing, complex tool paths and tool changes and, for casting, the need for patterns and tools. The approach works by slicing a 3D model, selectively printing a fluid onto a sheet of substrate material for each layer based on the model, flooding onto the substrate a powdered metal to which the fluid adheres in printed areas, clamping and aligning a stack of coated sheets, heating the stacked sheets to melt the powdered metal and fuse the layers of substrate, and removing excess powder and unfused substrate.

Abstract: A particulate for an additive manufacturing technique includes metallic particulate bodies with exterior surfaces bearing a polymeric coating. The polymeric coating is conformally disposed over the exterior surface that prevents the underlying metallic body from oxidation upon exposure to the ambient environment by isolating the metallic particulate bodies from the ambient environment. Feedstock materials for additive manufacturing techniques, and methods of making such feedstock, are also disclosed.

Abstract: Provided are a rare-earth permanent magnet whose magnet density after sintering is very high and a method for manufacturing a rare-earth permanent magnet. Thus, a magnet raw material is milled into magnet powder, and then, a compound 12 is formed by mixing the magnet powder thus milled with a binder. Next, the compound 12 thus formed is subjected to a hot-melt molding onto a supporting substrate 13 so as to form a green sheet 14 molded to a sheet-like shape. Thereafter, while the green sheet 14 thus molded is softened by heating, magnetic field orientation is carried out by applying a magnetic field to the green sheet 14 thus heated; and further, the green sheet 14 having been subjected to the magnetic field orientation is calcined by a vacuum sintering, which is further followed by a pressure sintering to produce a permanent magnet 1.

Abstract: Provided is a sliding member having: a back metal layer; and a sliding layer on the back metal layer. The sliding layer includes a porous sintered layer and a resin composition. The sintered layer includes Ni—P alloy phase and granular steel phase made of a carbon steel including 0.3-1.3 mass % of carbon and having a structure of: ferrite phase; and perlite phase, or perlite phase and cementite phase. The Ni—P alloy phase binds the steel phases with one another and/or binds the steel phases with the back metal layer. The steel phase includes a low perlite phase part in a surface. The low perlite phase part has an area ratio of the perlite phase lowered by 50% or more compared with a total area ratio of the perlite phase and the cementite phase at a central part of the steel phase when observed in a cross-section.
