摘要

The method for producing components from refractory metals, comprises melting powdered components from the refractory metals by electron beam melting in point-wise manner, and developing the components in its end form or in a near-net-shape contour. The electron beam melting is a generative electron beam melting for producing the components from the materials such as molybdenum, tantalum, rhenium and tungsten and its alloys. The melting is carried out in point-wise manner and a high-frequency digital deflection technique is carried out for forming the components.

The electron beam melting is a generative electron beam melting for producing the components from the materials such as molybdenum, tantalum, rhenium and tungsten and its alloys. The melting is carried out in point-wise manner and a high-frequency digital deflection technique is carried out for forming the components to the application and/or is produced on the basis of the digital deflection technique of the products. The production of the component is carried out in a double-walled vacuum chamber.
