Metallic　glass　(MG)　lattice　structure　is　expected　to　exhibit　high　specific　strength,　high　impact　resistance,　and　corrosion　resistance　due　to　the　combined　advantages　of　MG　and　lattice　structure.　Laser　powder　bed　fusion　(LPBF)　was　employed　to　prepare　the　MG　lattice　structure　in　the　present　research.　Firstly,　the　LPBF　processing　parameters　were　optimized　to　prepare　nearly　full　amorphous　state　alloy　(Zr41.2Ti13.8Cu12.5Ni10Be22.5)　accompany　with　the　high　relative　density.　Under　the　optimal　parameters,　the　LPBF-processed　MG　rod　with　Φ　=　1　mm　could　achieve　a　high　strength　of　1428　MP　and　a　plastic　deformation　strain　of　∼2　%.　Two　kinds　of　MG　lattice　structures　including　body-centered　cubic　(BCC)　and　thin　wall　(TW)　were　fabricated,　and　their　microstructure　characters　and　mechanical　properties　were　investigated.　The　LPBF-processed　MG　TW　lattice　structure　exhibited　a　more　faithful　reproduction　of　the　designed　model　than　the　BCC　lattice　structure.　Remarkable,　TW　lattice　structure　showed　relatively　higher　specific　strength　(2.55×105　Nm/kg)　and　obvious　plastic　deformation　strain　(2　%)　compared　with　the　BCC　lattice　structure,　which　could　be　attributed　to　the　less　tension　stress　distribution　and　the　multiplication　of　shear　bands　within　the　thin　wall　intersection　regions　under　compression　load.　©　2024　Elsevier　B.V.
