Metallurgical Characterization of SS 316L Repurposed by Wire Plus Arc Additive Manufacturing

This research aims to analyze the microstructures and mechanical characteristics of stainless steel (SS) 316L repurposed by wire plus arc additive manufacturing (WAAM). The SS is deposited on a 316 substrate, which can be repurposed. material underwent optical microscopy, X-ray diffraction, tensile test, results indicate that it features cellular columnar dendrites at bottom equiaxial grains top. strength interface region between (DM) base (BM) highest (559 ± 4.16 MPa vs. 510 4.93 in DM 540 2.65 BM), indicating BM layers are strongly bonded. All from defect observation, microstructures, confirm potential WAAM process for repurposing.
