Beschreibung
Zusammenfassung:	The invention relates to a component having a matrix phase consisting of at least one material selected from a group comprising molybdenum, a molybdenum-based alloy, tungsten, a tungsten-based alloy and a molybdenum-tungsten based alloy, manufactured by a laser- or electron beam in an additive manufacturing process, the molybdenum content, tungsten content, or the total content of molybdenum and tungsten being greater than 85 at%, and the component containing particles, the melting point of which lies above the melting point of the matrix phase. 本发明涉及一种构件，具有由至少一种选自包括钼、钼基合金、钨、钨基合金及钼-钨基合金的组中的材料构成的基体相，该基体相由激光或电子束在添加物方式制造方法中制成，其中钼含量、钨含量或者钼与钨的总含量大于85at％，且其中该构件含有微粒，这些微粒的熔点高于该基体相的熔点。
