Selective Electron Beam Melting
2020Selective electron beam melting (SEBM) is a type of additive manufacturing (AM), which is categorized into powder bed fusion (PBF) in ISO52900 as well as selective laser melting (SLM). SEBM is denoted by PBF-EB, meaning electron beam-based PBF. Formerly, SEBM was denoted by the term “E-PBF,” but currently “PBF-EB” is used. To emphasize that the process

Processing of tungsten through electron beam melting
Journal of Nuclear Materials, 2021Abstract Additive manufacturing (AM) presents a new design paradigm for the manufacture of engineering materials through the layer-by-layer approach combined with welding theory. In the instance of difficult to process materials such as tungsten and other refractory metals, AM offers an opportunity for radical redesign of critical components for next-

Modelling and simulation of electron beam melting
Production Engineering, 2009In recent years, the scientific and industrial relevance of additive layer manufacturing (ALM) has grown. In the metal area of ALM, the capacity of laser technologies is noticeably limited. This is mainly due to an inertial beam deflection device, which is also referred to as a mirror galvanometer.

Laser and electron-beam melted amorphous layers
Journal of Materials Science, 1981Metallic-glass layers were produced on metallic bulk material using laser or electron beam melting. The requisite composition (FeCr12)80(C,B)20 for steel and NixNb(100−x), (x = 30 to 60) for niobium was obtained by coating the substrate prior to melting. X-ray, scanning electron microscopy, transmission electron microscopy and calorimetric methods were

Fabricating Copper Components with Electron Beam Melting
AM&P Technical Articles, 2014Abstract The ability to make components from copper and copper alloys via additive manufacturing is spurring a range of novel applications. Although the high thermal conductivity of copper presents challenges for direct AM processes, fully dense copper components with complex geometries have been demonstrated.

Practical Implications of Electron-Beam Surface Melting
JOM, 1982The use of laser/electron-beam techniques to glaze large surface areas is briefly reviewed. The properties thus obtained for a range of iron-based alloys is discussed. Recent results show that electron-beam glazing can extend the wear life of certain cemented carbide materials and preliminary results indicate that glazed tool steels show enhanced ...

Purification of iridium by electron beam melting
Journal of Alloys and Compounds, 2008The purification of iridium metal by electron beam melting has been characterized for 48 impurity elements. Chemical analysis was performed by glow discharge mass spectrographic (GDMS) analysis for all elements except carbon, which was analyzed by combustion. The average levels of individual elemental impurities in the starting powder varied from 37 μg/
