摘要

本研究旨在分析采用焊丝加电弧增材制造（WAAM）改造的不锈钢（SS）316L的微观结构和力学特性。不锈钢316L焊丝沉积在不锈钢316基材上，可重新使用。该沉积材料经过光学显微镜、X射线衍射和拉伸测试，结果表明，其底部具有细胞状和柱状枝晶，顶部具有等轴晶粒。沉积材料（DM）和基底材料（BM）之间的界面区域的抗拉强度最高（559±4.16MPa，DM为510±4.93MPa，BM为540±2.65），表明BM和沉积层牢固结合。缺陷观察、微观结构和机械特性的所有结果都证实了WAAM工艺重新利用的潜力。

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