| Abstract Scope |
Laser pulses create extreme conditions in small regions of the metal substrate, forming unique structures across the macro to micro scale. These structures are formed at the surface, enabling local modification of surface texture and microstructure with minimal effect on the substrate. In this work, the surface structure is altered through a series of laser pulses creating a textured surface. Surface profile development is understood through computational fluid dynamics simulations in FLOW-3D replicating the structures formed to determine the controlling factors and predict depth of penetration. Microstructural characterization is performed to validate modeling results and relate laser parameters to solidification behavior and observed surface structures. These results may be used in future work to design tailored surface texture and microstructures in local regions. |
