Oxide Modified Iron in Electron Beam Powder Bed Fusion—From Processability to Corrosion Properties [PDF]
Alloys, 2022 Additive manufacturing (AM) processes are not solely used where maximum design freedom meets low lot sizes. Direct microstructure design and topology optimization can be realized concomitantly during processing by adjusting the geometry, the material composition, and the solidification behavior of the material considered. However, when complex specific
