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.

Parametric study and surface morphology analysis of electron beam selective melting
Rapid Prototyping Journal, 2018Purpose This paper aims to study the effect of processing parameters and the fundamental mechanism of surface morphologies during electron beam selective melting. Design/methodology/approach From the powder-scale level, first, the discrete element method is used to obtain the powder bed distribution that is comparable with the practical condition ...

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.

Selective electron beam melting (SEBM) is an additive manufacturing method used to produce complex parts in a layer-by-layer process utilizing Ti6Al4V powder. To improve the very good properties of built parts even more and to use the full capacity of the process, the fundamental understanding of the beam powder interaction is of essential relevance ...

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

Grain structure evolution in Inconel 718 during selective electron beam melting
Materials Science and Engineering: A, 2016Abstract Selective electron beam melting (SEBM) is an additive manufacturing method where complex parts are built from metal powders in layers of typically 50 µm. An electron beam is used for heating (about 900 °C building temperature) and selective melting of the material.

In vivo performance of selective electron beam‐melted Ti‐6Al‐4V structures
Journal of Biomedical Materials Research Part A, 2009AbstractHighly porous titanium structures are widely used for maxillofacial and orthopedic surgery because of their excellent mechanical properties similar to those of human bone and their facilitation of bone ingrowth. In contrast to common methods, the generation of porous titaniumproducts by selective electron beam melting (SEBM), an additive ...

Simulation of Selective Electron Beam Melting Processes
2011In strahlbasierten additiven Herstellungsverfahren werden Metallpulver schichtweise selektiv geschmolzen. Die Dichte des auf diese Weise erhaltenen Materials, die räumliche Auflösung, wie auch die Oberflächenrauigkeit der fertigen Komponenten resultieren aus einem komplexen Zusammenspiel von Material- und Prozessparametern.
