Abstract Scope |
The production of additively manufactured magnesium alloys was achieved by laser powder bed fusion (LPBF). Herein, Mg-Al alloys that also include compositions with a hyper-loading of solute, are presented. The microstructure and corrosion behaviour of the specimens was characterised, and also contrast to the conventional alloy counterparts. The LPBF prepared specimens were shown to possess a unique microstructure comprising of fine grains and a crystallographic texture that was unique to cast or wrought Mg-alloys. Opportunities for optimisation of magnesium alloys using the LPBF process, including unique alloy compositions and the opportunity to directly generate components in net shape, are elaborated. |
