SUMMARY

In this study, the effects of layer orientation on the mechanical properties of 316L stainless steel (SS) fabricated via a DED additive manufacturing process were investigated. Microstructure was analyzed and quasi-static tensile tests were conducted on DED 316L SS specimens fabricated in orientation increments of 15 degrees with respect to the loading direction. Specimens were tested in their as-built condition without any post process heat treatments. Yield, ultimate tensile strength (UTS), and maximum elongation were measured.
