Application of computational thermodynamics and kinetics to alloy design for additive manufacturing
ABSTRACT
During the past couple of years, the number of alloys commercially available for metal additive manufacturing (AM) has increased considerably. Compared to the amount of alloy grades available for conventional manufacturing methods, however, the number is still low and is one of the limiting factors for the broad industrial implementation of metal AM. Computational materials design can help accelerate the development of tailored AM materials and the focus of this presentation will be on the use and application of computational thermodynamics and kinetics to alloy development for AM. Examples of our ongoing research activities will be presented with focus on the solidification behavior, solid-state phase transformation and precipitation kinetics during AM and post-processing of steels.
BIOGRAPHY
Greta Lindwall is an Associate Professor at the Department of Materials Science and Engineering in KTH Royal Institute of Technology in Sweden. Her background is in computational thermodynamics and kinetics and how such computational tools can be developed and applied to alloy development. Dr. Lindwall’s current research focuses on materials design for metal additive manufacturing. Her group combines computational approaches with advanced materials characterization to increase the understanding and predictability of the structure evolution during additive manufacturing. She received her M.S. in Engineering Physics from LTH Lund University in and her PhD in Materials Science from KTH. Prior to her current appointment, she was a postdoctoral researcher at Penn State’s Department of Materials Science and Engineering and at the National Institute of Standards and Technology.
