“Additive Manufacturing: Mechanics, Metallurgy, and Machine Learning ”
Allison Beese, Associate Professor of Materials Science and Engineering and Mechanical Engineering; Director, Additive Manufacturing & Design Graduate Program, Penn State
Abstract
The unique thermal histories (i.e., rapid solidification followed by repeated thermal cycles with the addition of layers) seen in laser-based additive manufacturing (AM) 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 on investigating the impact of processing on microstructures and resultant failure behavior of additively manufactured alloys. Additionally, I will describe our work on developing tools to design functionally graded materials in which the composition is spatially tailored to impart site-specific properties within a 3D component.
