Single-Track Melt-Pool Measurements and Microstructures in Inconel 625
Supriyo Ghosh, Li Ma, Lyle E. Levine +4
We use single track laser melting experiments and simulations on Inconel 625 to estimate the dimensions and microstructures of the resulting melt pools. Our work is based on a desi…
Formation of Nb-rich droplets in laser deposited Ni-matrix microstructures
Supriyo Ghosh, Mark R. Stoudt, Lyle E. Levine +1
Ni-rich cells and Nb-rich eutectic droplets that form during laser power bed fusion solidification of Ni-Nb alloys are studied using experiments and simulations. Finite element…
Educational commitment and social networking: The power of informal networks
Justyna P. Zwolak, Michael Zwolak, Eric Brewe
The lack of an engaging pedagogy and the highly competitive atmosphere in introductory science courses tend to discourage students from pursuing science, technology, engineering, a…
Application of Finite Element, Phase-field, and CALPHAD-based Methods to Additive Manufacturing of Ni-based Superalloys
Trevor Keller, Greta Lindwall, Supriyo Ghosh +11
Numerical simulations are used in this work to investigate aspects of microstructure and microsegregation during rapid solidification of a Ni-based superalloy in a laser powder bed…
Crystal asymmetry induces single-atom chain formation in gold nanowires
F. Tavazza, A. Hasmy, L. E. Levine +4
We performed density functional theory and tight-binding molecular dynamics calculations to investigate the formation of suspended linear atom chains when stretching gold nanowires…
