Beschreibung
Zusammenfassung:	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 MoO2 and/or MoO3; in the case of tungsten and the tungsten-based alloy, for WO2 and/or WO3; and, in the case of the molybdenum-tungsten-based alloy, for at least one oxide from the group of MoO2, MoO3, WO2 and WO3. The alloying element, or at least one of the alloying elements, is present both in at least partially unoxidized form and in oxidized form.
