A component has a matrix phase composed of at least one material selected from the group molybdenum, a molybdenum-based alloy, tungsten, a tungsten-based alloy and a molybdenum-tungsten-based alloy. The component is manufactured using a laser or electron beam in an additive manufacturing process. The molybdenum content, the tungsten content or the total content of molybdenum and tungsten is more than 85 at %, and the component contains particulates having a melting point above the melting point of the matrix phase.

Additively-manufactured refractory metal component, additive manufacturing process, and powder

A component has a solid structure that is manufactured using a laser or electron beam in an additive manufacturing process. The solid structure is formed from at least one material selected from the group consisting of molybdenum, a molybdenum-based alloy, tungsten, a tungsten-based alloy, and a molybdenum-tungsten-based alloy. The component includes one or more alloying element which at least in the temperature range ≥1500° C. has/have a reducing effect, as follows: in the case of molybdenum and the molybdenum-based alloy, for MoOand/or MoO; in the case of tungsten and the tungsten-based alloy, for WOand/or WO; and, in the case of the molybdenum-tungsten-based alloy, for at least one oxide from the group of MoO, MoO, WOand WO. The alloying element, or at least one of the alloying elements, is present both in at least partially unoxidized form and in oxidized form.

A casting insert includes a casting insert wall formed substantially of a liquid-phase-sintered refractory metal alloy, a cavity formed by the casting insert wall, and at least one cooling duct, which is different from the cavity and which is formed at least partly within the cavity and/or which is formed at least partly within the casting insert wall. The casting insert wall has a wall thickness which can be defined as a normal distance between a point of the casting insert wall which faces the cavity and a point on an outer surface of the casting insert wall. The wall thickness is, at least in sections, less than 25% of a diameter of the casting insert.

Casting insert and production method

An x-ray and/or gamma radiation absorbing slat, for use in an anti-scatter grid having a layer configuration, includes a film-shaped substrate of a metallic material on the basis of at least one heavy metal and at least one coating layer of a material on the basis of at least one metal from the group tin, antimony, tantalum, tungsten, rhenium, iridium, platinum, gold or bismuth. The material of the coating layer differs from the material of the film-shaped substrate. An anti-scatter grid for x-ray and/or gamma radiation, a method for producing an x-ray and/or gamma radiation absorbing slat and a method of producing an anti-scatter grid, are also provided.

Anti-scatter grid

A method for producing a shaped body from a metallic infiltrated composite, includes a first step in which a shaped body framework, some regions of which have an open pore framework structure, is produced from a powder or from a powder mixture having a primary component of a first metal or of a first metal alloy, in that the powder or the powder mixture is applied in layers, at least partially locally melted at predefined sites by a selective beam melting method and binds together upon solidification. In a second step, the shaped body framework is infiltrated with a melt of a second metal or metal alloy which melts at a lower temperature than the first metal or metal alloy.

A collimator for x-ray, gamma, or particle radiation has a plurality of collimator elements made of a tungsten-containing material to reduce scattered radiation. At least one collimator element consists of a tungsten alloy having a tungsten content of 72 to 98 wt.-%, which contains 1 to 14 wt.-% of at least one metal of the group Mo, Ta, Nb and 1 to 14 wt.-% of at least one metal of the group Fe, Ni, Co, Cu. The collimator also has very homogeneous absorption behavior at very thin wall thicknesses of the collimator elements.

Collimator for x-ray, gamma, or particle radiation

Semi-finished or finished parts are made from a molybdenum alloy with intermetallic phases, preferably molybdenum-silicide, molybdenum-boron-silicide, optionally also molybdenum-boride phases. Starting from mechanically alloyed powder, hot compacted material exhibits superplastic forming behavior. It is thus possible to lower the forming temperature by at least 300&#xb0; C., thus permitting processing on conventional plants.

Process for the production of a molybdenum alloy

A shaped part or article of manufacture is formed of a selected gamma titanium aluminide alloy with outstanding mechanical properties which can be produced particularly economically. First, a semi-finished article is formed in a hot forming process with a degree of deformation of greater than 65%. Then the semi-finished article is shaped with the alloy being in a solid-liquid phase by applying mechanical forming forces during at least part of the shaping process.
