Mechanics of Additively Manufactured Metals

Monday, June 3, 2024 | 11:30 a.m. - 12:30 p.m.

Additive manufacturing (AM) of metals has potential applications in a number of areas, e.g., to address supply-chain issues, enable significant lightweighting of components, and provide a route for fabricating custom biomedical implants. However, the laser-based layer-by-layer AM processing of metal alloys results in microstructures that may contain phases, grain morphologies, or internal pores different from those seen in their conventionally processed counterparts. These microstructures dictate the resulting mechanical properties of the alloys; thus, to enable the adoption of AM for structural applications, an understanding of the links between microstructure and deformation and/or fracture is required to reliably design against failure. In this talk, I will present our work in three general areas: using in situ process monitoring to link processing signatures to defects and mechanical properties, unraveling the impact of internal defects on the multiaxial failure behavior of additively manufactured metallic materials, and the development of a framework for designing functionally graded materials in which the composition is spatially tailored to impart site-specific properties within a 3D component.
