Crystallographic orientation dependence of Charpy impact behaviours in stainless steel 316L fabricated by laser powder bed fusion

Despite the extensive research on the mechanical properties of stainless steel 316L (SS316L) produced by laser powder bed fusion (LPBF), only a handful of studies have investigated its impact performance even though it is critical for structural applications experiencing rapid loading. In this study, the crystallographic-orientation-dependent Charpy impact behaviours of LPBF-SS316L were systematically investigated. Samples with their...
