20.500.12556/RUL-166519 Enhancing directed energy deposited AL5356 through in situ workpiece vibrations This study explores an innovative method to enhance Directed Energy Deposition (DED) of aluminum 5356 products by integrating an electromagnetic vibration system into the DED setup. The application of vibrations significantly improved surface quality, reducing surface waviness and increasing building efficiency by 14%, from 78.5% to 92.25%.Gas porosity was reduced from 1.5 ± 0.04% in as-built (AB) components to 0.34 ± 0.07% in vibration-assisted (VA) parts. Tensile tests showed a marked reduction in anisotropy, with the tensile strength deviation between the x and z directions decreasing to less than 0.4% for vibration-assisted samples, compared to 7.9% for as-built ones. Additionally, secondary phase analysis revealed a homogenization effect, with magnesium- and iron-rich precipitates displaying a finer dispersion (3.57 ± 3.42 μm²) compared to 11.28 ± 12.49 μm² in as-built parts. Overall, the findings highlight the potential of vibration-assisted DED to improve part properties, reduce defects, and advance the DED manufacturing process. directed energy deposition (DED) vibrations residual stress gas porosity grain refinement aluminium alloys usmerjeno nanašanje z energijo vibracije zaostale napetosti plinska poroznost udrobnjevanje kristalnih zrn aluminijeve zlitine true false false Angleški jezik Slovenski jezik Članek v reviji 2025-01-16 11:47:56 2025-01-16 11:48:05 2025-04-09 14:16:02 0000-00-00 00:00:00 2024 0 0 PDF format Str. 43-47 no. 2 Vol. 49 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2024-12-15 620.1:621.3 2620-147X 10.24867/ATM-2024-2-005 222618627 https://atm-journal.uns.ac.rs/index.php/atm/article/view/ATM-2024-2-005 1 a0233bcc-d3f6-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=198181 Imsirovic_..._Enhancing.pdf Imsirovic_..._Enhancing.pdf 1 16A381A7DDFA29CABAC5E369F7559E9B c65e2514461d26f435fa6479f49936c05149bc2b6af2f530cb97c294f6a85f9f d19f2153-d3f6-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=198182 Fakulteta za strojništvo 0 0 0
