A sintered magnet and a method for producing the same are provided. The method includes producing an R—Fe—B-based magnet powder by a reduction-diffusion method, adding a R—Al—Cu powder as a sintering agent to the R—Fe—B-based magnet powder to form a mixed powder, wherein the R—Al—Cu powder is an alloy of R, Al and Cu, and R is Nd, Pr, Dy, Tb or Ce, and sintering the mixed powder to form a sintered magnet.

A transient liquid phase (TLP) composition includes a plurality of first high melting temperature (HMT) particles, a plurality of second HMT particles, and a plurality of low melting temperature (LMT) particles. Each of the plurality of first HMT particles have a core-shell structure with a core formed from a first high HMT material and a shell formed from a second HMT material that is different than the first HMT material. The plurality of second HMT particles are formed from a third HMT material that is different than the second HMT material and the plurality of LMT particles are formed from a LMT material. The LMT particles have a melting temperature less than a TLP sintering temperature of the TLP composition and the first, second, and third HMT materials have a melting point greater than the TLP sintering temperature.

Systems of electrical devices with high-resolution components and methods of fabricating the electrical devices using micro-molding processes are described. Small foot print electrical devices can be achieved by fabricating components with highly conductive materials, and with closely spaced components.

The invention relates to a method of forming a 3-dimensional solid object, comprising the steps: a) cold spraying one or more metallic powder to form a solid three dimensional item; b) thermally sintering the item such that a portion of the sprayed powder liquefies and reduces spaces between, and/or non-adhesion of, one or more solid portions of the item; and c) causing or allowing the portion of the sprayed powder that liquefied on heating, to become solid.

The disclosure relates to sintering compositions that can be used in three-dimensional printing or additive manufacturing processes. The sintering compositions generally include one or more metallic iron-containing powders and a minor amount of a boron-containing powder as a sintering aid. Sintered models or products formed from the sintering compositions have substantially improved density and surface roughness values relative to models formed without the boron-containing powder.

The invention relates to a 3D printer. The 3D printer includes a first feeder containing a metallic powder first print material, a second feeder containing a metallic powder second print material, delivery means that sprays the print materials, a holder holding a substrate, and a controller. As the print materials are sprayed from the delivery means the controller, which is computerized, adjusts the relative disposition of the delivery means and substrate, and the controller controls the first and second feeders to each feed their print material to the delivery means, so that the print materials form a 3D article on the substrate wherein different parts of the 3D article have different characteristics due to the different print materials or proportions thereof being used for different portions of the 3D article.

The present invention relates to a method for the economic production of metallic parts, with high flexibility in the geometry attainable. It also relates to the material required for the manufacturing of those parts. The method of the present invention allows for a very fast manufacturing of the parts. Also some forming technologies applicable to polymers can be used. The method allows for the fast and economic production of complex geometry metallic parts.
