| Abstract Scope |
With the growing trend of industrial intelligence and pollution reduction, laser powder bed fusion (LPBF) has great potential for fabricating high-performance Mg alloy components with complex shapes. The extremely fast cooling rate of the LPBF process contributes to rapidly solidified non-equilibrium microstructure with fine grains and allows the addition of rare earth (RE) elements out of equilibrium saturation. Mg-RE series alloys with gadolinium (Gd) and yttrium (Y) as the main additives are considered to be able to achieve high strength by significant precipitation strengthening that is ordinarily realized through a solution heat treatment and a subsequent aging treatment in order to enable the precipitation of nanoscale β′ from supersaturated solid solution. Here we proposed a design method for optimise the composition of printed Mg alloy to achieve high precipitate strength. |
