Auxetic cellular structures through selective electron-beam melting
physica status solidi (b), 2010This paper is concerned with the build up and characterization of well-defined auxetic structures (negative Poisson ratio) from Ti-6A1-4V through selective electron-beam melting (SEBM). SEBM is a rapid prototyping/manufacturing technique allowing for the direct translation of CAD models to real world objects.

Diverse microstructure of Ti6.5Al2Zr1Mo1V fabricated via electron beam selective melting
Materials Letters, 2021Abstract Ti6.5Al2Zr1Mo1V was fabricated via electron beam selective melting (EBSM) with different process parameters to study the diversity of microstructure. Results demonstrate that samples with a flat surface can be obtained when the ratio of beam current to scanning speed fluctuated between 5.0 and 7.5 as other parameters were fixed.

Selective Electron Beam Melting of Oxide Dispersion Strengthened Copper
Advanced Engineering Materials, 2018An 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, 2008Cellular 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 ...

Selective electron beam melting of a copper-chrome powder mixture
Materials Letters, 2018Abstract 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
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

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 ...
