Abstract Scope |
In this presentation, the annealing response of 316L manufactured with both laser powder bed fusion (LPBF) and wire-arc additive manufacturing (WAAM) is discussed in the context of microstructural evolution and mechanical properties. Because AM comprises several technologies that differ in heat source, feedstock, and scan strategy, among other build variables, the final products can exhibit a range of thermal histories. These unique thermal histories can subsequently influence as-built properties and annealing response of AM materials, most notably those manufactured with different AM deposition processes. Characterization methods including differential scanning calorimetry (DSC), optical microscopy, x-ray diffraction (XRD), and tensile testing are utilized to better understand how deposition history affects the extent of annealing. Comprehensive characterization results are presented to provide insight into the necessary post-build processing required to achieve desired properties for AM materials |
