Abstract Scope |
The laser-powder bed fusion additive manufacturing process for metallic parts belong to a novel and innovative production technology. However, understanding and predicting the mechanical response of the produced additively manufactured (AM) components is crucial for engineering applications. The objective of this investigation is to produce high quality residual strain measurements in order to provide input on the controlled benchmark tests (AM-Bench) for AM specimens. In support of this effort, we performed energy dispersive X-ray diffraction measurements on AM Inconel 625 and 15-5 stainless steel components. Our aim is to use the measured lattice parameter to calculate and profile the residual strains on the parts. Our results will be used as a strong validation challenge to modeling agencies. During this presentation, the results on the residual strain along the build and the longitudinal direction will be discussed, as well as the shear residual strain component. |
