Abstract Scope |
One important length scale that is associated with the additively manufactured metals is the build dimension, leading to the location-dependent microstructures and properties. In each specific location, multiple microstructural length scales influence the deformation behavior. In this talk, we report our recent progresses in studying the location-dependent deformation kinetic parameters of various additively manufactured metals. We compare materials made by several representative additive manufacturing techniques, including laser powder-bed-fusion, laser directed=energy-deposition, and wire arc additive manufacturing. Several examples of materials are also studied. Our studies suggest that additive manufacturing techniques have strong influence on the location-dependent mechanical behavior, primarily due to the very different thermal histories associated with different techniques. We discuss the implications of these results to practical applications and propose strategies to mitigate the location-dependent behavior. |
