Comparison study on additive manufacturing (AM) and powder metallurgy (PM) AlSi10Mg alloys. JOM, 70(5), 644-649. doi:10.1007/s11837-018-2793-4 | Journal: | JOM | Abstract: | The microstructural and mechanical properties of AlSi10Mg alloys fabricated by additive manufacturing (AM) and powder metallurgy (PM) routes were investigated and compared. The microstructures were examined by scanning electron microscopy assisted with electron-dispersive spectroscopy. The crystalline features were studied by x-ray diffraction and electron backscatter diffraction. Room-temperature tensile tests and Vickers hardness measurements were performed to characterize the mechanical properties. It was found that the AM alloy had coarser Al grains but much finer Si precipitates compared with the PM alloy. Consequently, the AM alloy showed more than 100% increment in strength and hardness compared with the PM alloy due to the presence of ultrafine forms of Si, while exhibiting moderate ductility. | URI: | https://hdl.handle.net/10356/142122 | ISSN: | 1047-4838 | DOI: | 10.1007/s11837-018-2793-4 | Schools: | School of Mechanical and Aerospace Engineering | Research Centres: | Singapore Institute of Manufacturing Technology | Rights: | © 2018 The Minerals, Metals & Materials Society.
