Scanning method of filling lines in electron beam selective melting
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2007Electron beam selective melting (EBSM) is a new kind of direct metal rapid manufacturing technology, which can be regarded as the integration of electron beam manufacturing and rapid prototyping technologies. Because the electron beam has great impact on the powder and the requirement of full density and high melting point needed during the EBSM ...

Characterization of Ni-Based Superalloy Built by Selective Laser Melting and Electron Beam Melting
Metallurgical and Materials Transactions A, 2018Alloy718 specimens built by selective laser melting (SLM) and electron beam melting (EBM) were comparatively examined. The higher cooling rate resulted in a high dislocation density and interdendritic precipitates, which brought about inferior creep properties in SLM alloys.

Archival information storage by selective electron beam melting of structured targets
Journal of Vacuum Science & Technology B: Microelectronics Processing and Phenomena, 1987We demonstrate archival information storage by electron beam melting of selected elements within a two dimensional array of gold columns. The individual columns were 60 nm in diameter, 270 nm in height, and spaced on 130 nm centers. These columns could be selectively melted with a 40 nm diam, 175 nA, 7 kV electron beam in times less than 60 ns.

Basics of selective electron beam melting of iron aluminides
2021The Additive Manufacturing process (AM) of Selective Electron Beam Melting (SEBM) is, due to its near-net shape character, particularly suitable for materials with a poor machinability, such as iron aluminides. These materials, which belong to the class of intermetallic phases, are assigned a high potential for high-temperature applications. The reason
