Process physics, heat transfer, and microstructure prediction in metal AM
Tarasankar DebRoy is Professor of Materials Science and Engineering at Penn State and a foundational figure in metal AM process modelling. His group developed the open-access 3D transient thermal-fluid model that underpins much of the modern community's understanding of melt-pool dynamics and microstructure evolution in LPBF and DED. The 2018 Progress in Materials Science review he led — "Additive manufacturing of metallic components: Process, structure and properties" — remains the most-cited overview in the field. DebRoy has also done influential work on residual stress prediction, columnar-to-equiaxed transitions, and the physical limits of build-rate scaling.
