Fig. 5: Compressive mechanical property of geometrically complex components.
From: Manufacturing of high strength and high conductivity copper with laser powder bed fusion
a Compressive engineering stress-strain curves of the L-PBF fabricated sheet-based gyroid lattices made of pure Cu and 1.0 wt% LaB6 nanoparticles doped Cu powder feedstocks. b Comparison of the compressive yield strength against relative lattice density between the present results and previously published data of lattices made of Cu, Cu alloys and Cu based composites47,48,49,50,51. c Video camera frames during compression of pure Cu lattice. d Video camera frames during compression of 1.0LaB6-Cu lattice. The pure Cu lattice showed development of localized shear bands (identified by the arrows), which were not evident in 1.0LaB6-Cu lattice. Source data are provided as a Source Data file.
