Influence of Deposition Mode on Microstructural and Mechanical Properties of Wire Arc Additive Manufactured 308L Stainless Steel Structures
Journal of Materials Engineering and Performance(2023)
Abstract
The aim of this study is to investigate the impact of different metal deposition modes—spray (S), pulse (P), and pulse-switchback (PS)—on the metallurgical and mechanical properties of SS308L structures in wire arc additive manufacturing (WAAM). Three thin-walled structures were deposited using optimal process variables and inter-layer time delay. Through metallographic examination, it was found that the P-mode had the highest homogeneity (88.94
