      abstract     = {This study investigates the influence of heat treatment
                      (HT) at 900 °C on the fatigue resistance of 316L stainless
                      steel fabricated through selective laser melting (SLM).
                      Fully reversed, force-controlled fatigue tests were
                      conducted on both as-built (AB) and HTed specimens to assess
                      their cyclic deformation behavior and fatigue life. The
                      fatigue fracture mechanisms were analyzed through detailed
                      microstructural characterization using secondary electron
                      imaging in a scanning electron microscope (SEM) and laser
                      scanning confocal microscope LSCM. Results show that the HT
                      316L exhibited improved fatigue resistance and a longer
                      fatigue life compared to the AB 316L. Fatigue cracking along
                      dendritic columnar grains and the formation of slip bands
                      were identified as key microstructural features in both AB
                      and HT materials. In the AB material, the columnar dendritic
                      grains and cellular substructure appear to create weak
                      points at grain boundaries, facilitating fatigue crack
                      initiation due to localized strain in persistent slip bands.
                      However, HT at 900 °C effectively reduced the cellular
                      substructure, promoting the formation of high-angle grain
                      boundaries, which significantly enhanced the fatigue
                      resistance of HT 316L.},
