Pulsed Electron Beam Melting of Fe
MRS Proceedings, 1981ABSTRACTPulsed (50 nsec) electron beams with deposited energies of 1.1 2.4 J/cm2 have been used to rapidly melt a surface layer of Fe. Calculations show that this range of energies produces melt depths from 0.4–1.2 μm and melt times of 100–500 nsec.

Electron beam versus plasma melting
International Materials Reviews, 1986AbstractThe electron beam and plasma melting processes are critically reviewed and compared. The principles of each process as it applies to melting of metallic alloys are reviewed and the similarities and differences between the two processes are highlighted.

Electron beam melting of bearing materials
Surface and Coatings Technology, 1990Abstract This paper reports on a surface treatment method for the bearing materials AlSn6 which permits the use of this material without the overlay usually required. Microstructural refinement is achieved by means of a surface melting technique using an electron beam with successive rapid solidification. Extremely fine tin precipitates are formed in

Electron beam melting in biomedical manufacturing
2020Electron beam melting (EBM) is an additive manufacturing technique that uses an electron beam to selectively fuse and consolidate the metal powder. The final object is built up layer-by-layer according to a computer-aided design or, in case of customized biomedical implants, according to a computed tomography of the patient. This chapter introduces the

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

Additive vacuum electronics: Electron beam melting of copper
2017 Eighteenth International Vacuum Electronics Conference (IVEC), 2017The construction of vacuum electronic devices is an artisan process; it requires extremes of high precision machining and assembly and the tolerances and feature sizes become more exacting as the frequency increases. Merging of copper additive manufacturing and electropolishing technologies will produce low-cost, high-throughput fabrication techniques ...

Melt pool dynamics during selective electron beam melting
Applied Physics A, 2013Electron beam melting is a promising additive manufacturing technique for metal parts. Nevertheless, the process is still poorly understood making further investigations indispensable to allow a prediction of the part’s quality. To improve the understanding of the process especially the beam powder interaction, process observation at the relevant time ...

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/
