“…At present, 316L stainless steel and Inconel 718 nickel superalloy are the most commonly used materials in additive manufacturing. The mechanical properties of SLM-processed 316L steel and Inconel 718 alloy have been extensively researched [ 6 , 8 , 14 , 18 , 19 ]. Studying the interaction of such materials with hydrogen is a new attractive research field [ 20 , 21 , 22 ].…”

“…Liu et al [32] studied the effects of two scanning strategies (single-directional scanning and cross-directional scanning) on the solidification structure and crystallographic texture of SLM-manufactured IN718 alloy. Ravichander et al [33] identified the effect of scan strategy on residual stress and studied the metallurgical interactions between the mechanical and microstructural properties within the IN718 superalloy. Wang et al [34] optimized the process parameters for selective laser melting of Inconel 718 and further established the relationship equation between the relative density of SLMed samples and the energy density coupled by laser parameters.…”

“…The TPMS structures are used as shock absorbers in spacecrafts and high-speed trains due to their high energy absorption capabilities [ 5 , 6 ]. LPBF is one of the most widely used metal AM techniques to fabricate complex metal TPMS structures with high accuracy [ 7 , 8 , 9 , 10 , 11 ]. The LPBF is a layer-by-layer manufacturing process in which the laser beam selectively melts and joins the metal powder layers until the desired part is fabricated [ 11 , 12 , 13 ].…”
