Abstract: A mechanical surface treatment method for a workpiece includes using a multi-axis powered machine to actuate a deep rolling tool having a roller relative to the workpiece. The actuating includes applying the roller against a workpiece surface with a normal force sufficient to plastically deform the workpiece and translating the roller relative to the workpiece surface. The method includes concurrently applying an electrical current to the workpiece surface in a manner that produces an electroplastic effect at the workpiece surface and a near surface region. The electroplastic effect and the plastic deformation produce a refinement in a grain structure at the workpiece surface and near surface region and an increase in dislocation sources and tangles within the grain structure.

Abstract: The present disclosure provides improved additive manufacturing methods and systems. More particularly, the present disclosure provides advantageous additive manufacturing methods and systems for the production of hierarchical design optimized components (e.g., composite or composite-like materials). The present disclosure provides a methodology to produce hierarchical design optimized additively manufactured parts/materials that include an inhomogeneous structure with variable local mechanical properties across the entire volume. Hierarchical inhomogeneous structure/composite materials can be produced through a laser powder bed fusion (LPBF) process. A novel LPBF method can be used to obtain location-specific properties through in-situ controlling of the local cooling rate during the additive manufacturing process.
