Abstract Scope |
The behavior of additively manufactured (AM) materials is affected by many different microstructural characteristics such as grain structure, the distribution of alloying elements, and flaw population. Some of these characteristics are dominant over others in some circumstances depending on the loading scenario, the material, and the magnitude of the features among other variables. This work focuses on the effects of microstructural features on the structural properties and failure in AM alloy AlSi10Mg. Several experiments are presented that demonstrate the effects of various microstructural characteristics on strength, ductility, and fracture behavior. These interactions have been investigated through the analysis and alignment of several datasets from different experimental techniques. Measurements from scanning electron microscopy (SEM), X-Ray computed tomography (CT) and large numbers of high throughput tensile bars are compared. SNL is managed and operated by NTESS under DOE NNSA contract DE-NA0003525. |
