摘要： A molding die according to the present disclosure includes a tubular portion and a base portion that closes an end portion of the tubular portion at one side. A cut level difference Rδc1 in a roughness curve of an inner wall surface of the tubular portion is smaller than a cut level difference Rδc2 in a roughness curve of an inner wall bottom portion of the base portion. The cut level difference represents a difference between a cut level at a load length ratio of 25% in a roughness curve and a cut level at a load length ratio of 75% in the roughness curve.

摘要： The disclosure relates to a powder and a method for generating a component by a powder-bed-based additive manufacturing method, such as laser melting. The powder includes particles having a core and a shell. The particles have an alloy composition of the component. The concentration of higher-melting alloy elements is greater in the shell and the concentration of lower-melting alloy elements is greater in the core, wherein the surface of the particles is higher in comparison with particles with a constant alloy composition. This advantageously prevents the particles from caking together in the powder bed during the production of the component, and so the powder bed may also be subjected to high preheating temperatures of up to 1000° C.

摘要： A composite component may include a substrate including a first material and defining a surface; and at least one feature attached to the surface of the substrate. The at least one feature may include a second, different material attached to the surface using cold spraying. Cold spraying may include accelerating particles of the second material toward the surface without melting the particles.

摘要： The invention relates to a layer building process for the additive manufacture of at least one wall region of a component including applying at least one powder layer of a material to at least one building-up and joining zone of at least one movable building platform, carrying out a first solidifying step, in which the material is irradiated selectively with at least one energy beam, wherein irradiation parameters of the at least one energy beam are set so a molten bath is produced and a defect-affected wall region of the wall is produced, without applying a further powder layer, carrying out a second solidifying step, in which the defect-affected wall region produced in the first solidifying step is irradiated selectively with the at least one energy beam, lowering the building platform layer by layer by a predefined layer thickness, and repeating the steps above one or more times

摘要： A method includes powder forging and machining a workpiece that is fractured to divide the workpiece into separate components. In a green form in which the workpiece is formed of compacted powdered metal and has a body that is generally shaped as a parallelepiped with a pair of end faces. The body defines a bore, a pair of V-notches and a pair of channels. The V-notches are formed into the bore parallel to the central axis of the bore and cooperate to define a separation plane. Each of the channels is formed in an associated one of the end faces at a location where the separation plane intersects the end face. During forging, the channels are closed but create a stress riser that aids in directing the fracture when the components are separated from one another.

摘要： A blend including 50% to 95% reinforcing particles by weight, and 5% to 50% filler particles by weight, of the blend, wherein the reinforcing particles have mean particle size within 70% or less of the mean particle size of the filler particles is disclosed. Such blends can be used to prepare metal matrix composites that can be infiltrated with a binder to form harden composites that can be used for the manufacture of tools.

摘要： A method for producing a valve seat ring via powder metallurgy may include compacting a powder mixture including 4% by weight to 16% by weight particles of cobalt to form the valve seat ring. The method may also include sintering the powder mixture after compacting the powder mixture. Before compacting the powder mixture, 80% of the particles of cobalt may have a particle diameter of approximately 4.4 μm to 17.5 μm.
