The working environment of high-strength steel components produced by wire-arc additive manufacturing (WAAM) often faced challenges explosion and impact, but the microstructure evolution dynamic mechanical behavior WAAM were still unclear. In this study, low alloy (HSS) WAAM. Split Hopkinson Pressure Bar (SHPB) tests at different strain rates carried out on WAAM-HSS, specimens before after compression characterized techniques such as SEM, EDS, XRD, EBSD, etc. results showed that: as-built...
