Embodiment Construction

[0108] Sample according to prior art:

[0109] For experiments not according to the invention, spheroidized Mo and W powders were used. For both powders, a 15 to 40 μm sieve fraction was used. The O content of the Mo powder is 0.39 at%, and the C content is 0.01 at%, and the O content of the W powder is 0.34 at%, and the C content is 0.009 at%. Both powders were processed by means of a 400W SLM system, resulting in samples with dimensions 10 mm x 10 mm x 10 mm, and notched impact bending samples according to DIN EN ISO 148-1. Notched impact bending samples were constructed with upwardly directed notches in the substrate. Therefore, the fracture surface produced by the notched impact bending test is parallel to the construction direction. The system has constructed space heating. For the experiments, the substrate was heated to 800 °C.

[0110] SLM process in figure 1 is shown schematically. The control system controls inter alia the laser 1 , the laser mirror 2 , the co...

Abstract

The invention relates to a component comprising a plurality of individual powder particles, formed from Mo, a Mo-based alloy, W or a W-based alloy, which are melted together to form a solid structurevia an additive manufacturing method using a high-energy beam, wherein the component has an oxygen-content that is lower than or equal to 0.1 at%. The invention also relates to an additive manufacturing method, wherein the powder is produced via the melting phase and has a carbon-content in the region of greater than or equal to 0.15 at%. The components according to the invention are free from cracks and are characterised by a high intergranular strength.

Description

technical field [0001] The present invention relates to a component comprising a mass of individual powder particles of molybdenum (Mo), Mo-based alloys, tungsten (W) or W-based alloys which have been fused together by a high energy beam by an additive manufacturing process to A solid structure was obtained. The invention also relates to an additive manufacturing method for producing components and the use of powders in the additive manufacturing method. Background technique [0002] Due to the high melting point, low thermal expansion coefficient and high thermal conductivity of Mo, W and their alloys, they are suitable for a variety of different high-performance applications, such as for X-ray anodes, heat sinks, high-temperature heating zones, thrusters, extrusion dies , mold components for injection molding, hot runner molds, resistance welding electrodes or components for ion implantation systems. Furthermore, these elements have a high density, which ensures good shi...
