Selective Electron Beam Melting of Oxide Dispersion Strengthened Copper

Advanced Engineering Materials, 2018
An oxide dispersion strengthened (ODS) copper powder containing 5 vol% Al2O3 as finely dispersed particles is processed by selective electron beam melting (SEBM), a powder bed based additive manufacturing technology. Contrary to usual powder characteristics used for SEBM, the particles show a non‐spherical morphology and a copper oxide layer on their ...

Selective Electron Beam Melting of Cellular Titanium: Mechanical Properties

Advanced Engineering Materials, 2008
Cellular titanium seems to be a promising material for medical implant applications due to an elastic modulus comparable with human bone and an interconnected porosity which facilitates bone ingrowth. This paper reports the mechanical properties of non-stochastic cellular Ti-6Al-4V structures fabricated by Selective Electron Beam Melting depending on ...

Effect of reuse times on H13 powder properties processed by selective electron beam melting

Powder Metallurgy, 2022
The inconsistency of high material cost and powder properties are the primary barriers to widespread adoption of metal additive manufacturing. Obviously, powder reuse without affecting the properties of the parts can reduce the cost burden. In this study,

Microstructure and Properties of Fe3Al/TiB2 Composites Formed by Selective Electron Beam Melting with Different Powder Processes

Advanced Engineering Materials
This study compares Fe–28Al–5Ti–1.3B composites fabricated via selective electron beam melting (SEBM) using ball‐milling and gas atomization powders. Ball‐milling powders achieve partial alloying; higher SEBM energy density (24 vs 15 J mm−3) is required ...

Selective electron beam melting of a copper-chrome powder mixture

Materials Letters, 2018
Abstract Additive manufacturing by selective electron beam melting (SEBM) was used to process a powder mixture consisting of elemental copper and chromium powders (nominal composition: Cu-25Cr). The melting temperatures of copper and chromium are largely different.

Selective Electron Beam Melting

2020
Selective 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
