Formation mechanisms and control strategies of metallurgical defects and microstructures during laser powder bed fusion of AlSi10Mg lattice structures

Formation mechanisms and control strategies of metallurgical defects and microstructures during laser powder bed fusion of AlSi10Mg lattice structures

Lattice structures fabricated using laser powder bed fusion (LPBF) are pivotal for lightweight design. However, their small dimensions and intricate geometry intensify the likelihood of defect formation, such as lack of fusion (LOF), near-spherical pores, and microstructural coarsening. In this stud...
