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.

Dual-detector electronic monitoring of electron beam selective melting
Journal of Materials Processing Technology, 2021Abstract Electron Beam Selective Melting (EBSM) is an advanced additive manufacturing technique used in many vital industrial fields. However, the lack of process monitoring and quality control is largely restricting the industrial application. The optical-based monitoring methods are hindered by the complex working conditions, such as intensive ...

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 ...

Electron-Beam Melting and Reuse of Metallic Materials
Metal Science and Heat Treatment, 2020We study the processes and mechanisms of electron-beam melting (EBM) used in the production of high-purity metals. We formulate the requirements that should be imposed on the EBM parameters for the production of high-quality materials and proposed some optimal modes.

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

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.

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 ...

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
