Effects of chamber oxygen concentration on microstructure and mechanical properties of stainless steel 316L parts by selective laser melting by Sun, Zhongji, Tan, Xipeng, Tor, Shu Beng

“…Three batches of SS316L samples with varying chamber oxygen concentrations of 0.08 mol%, 0.16 mol% and 0.24 mol% were fabricated by SLM. Tensile and Vickers hardness tests were conducted. Backscatter Electron Microscopy was employed to elucidate the mechanisms of these amorphous nano-particles on the overall mechanical performance.…”
