| Abstract Scope |
Certification requirements generally involve meeting engineering and physics
requirements tied to the functional requirements of the engineering component and finally process and product qualification. In this presentation, the results of a study quantifying the microstructure and constitutive behavior of 316L SS fabricated using an EOS 400 – Laser-Powder-Bed Additive Manufacturing(AM) method is presented. The mechanical behavior of the AM built 316L SS was characterized using compression testing as a function of strain rate, temperature, and across a laser-laser overlap build region for this 4-laser EOS machine. The dynamic damage evolution and failure response of the AM-316L SS material as a function of position away from and across the build overlap region, as well as wrought 316L SS, was probed using flyer-plate impact driven spallation experiments. The damage evolution of the AM-316L SS and wrought-316L SS was characterized using optical metallography and electron-back-scatter diffraction (EBSD). |
