| Abstract Scope |
Lattice structures of Mg-RE and Zn-Mg alloys with different strut sizes were manufactured by Laser Powder Bed Fusion (LPBF) process. The relationship between processing conditions and the microstructure was carefully analysed by means of X-ray µtomography, scanning electron microscopy and electron-backscatter diffraction as well as transmission electron microscopy. In addition, the mechanical properties and the fracture mechanisms were ascertained by means of in situ compression tests within an X-ray µtomography system in lattices that have been immersed in simulated body fluids for different time periods. These results were used to ascertain the influence of processing parameters, lattice dimensions and heat treatments on the mechanical properties and corrosion resistance of lattice structures of Mg-RE and Zn-Mg alloys manufactured by LPBF. |
