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 ...

Investigation on Surface Roughness in Electron Beam Selective Melting by Mesoscale Model
Materials Science Forum, 2021Modeling and simulation in meso-scale have been used to investigate the complicated physics involving powder behaviors during the forming process in electron beam selective melting. But it is difficult to quantitatively predict the forming quality of parts due to the huge calculation amount for multi-layer and multi-pass cases.

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.

Hierarchical microstructure of a titanium alloy fabricated by electron beam selective melting
Journal of Materials Science & Technology, 2020Abstract Here, a near alpha-type Ti6.5Al2Zr1Mo1V alloy has been fabricated by electron beam selective melting (EBSM). Near-equiaxed grains existed in the first few layers, whereas elongated columnar prior β grains almost parallel to the building direction formed in the subsequent built layers.

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
