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.
