DED microstructure-property relationships and functionally-graded AM alloys
Allison Beese is Professor of Materials Science and Engineering and Mechanical Engineering at Penn State, where she leads the Multiscale Mechanics and Materials Laboratory. Her group is widely cited for systematic process-structure-property studies of directed energy deposition (DED-laser, LENS) — including foundational work on functionally-graded transitions between stainless steels and nickel superalloys, dissimilar-metal joints, and gradient titanium alloys. She was a key co-author of the 2018 DebRoy Progress in Materials Science review (debroy-2018-review), contributing the constitutive-modelling and mechanical-properties sections that link microstructure to ductility and fracture in AM metals. Her work on plastic anisotropy and tension-compression asymmetry of AM metals has influenced both qualification practice and ICME framework development. She is an ASME Fellow and has received the NSF CAREER and ONR Young Investigator awards.
