Beschreibung
Zusammenfassung:	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.
