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…
Entanglement dynamics following a sudden quench: an exact solution
Supriyo Ghosh, Kumar S. Gupta, Shashi C. L. Srivastava
We present an exact and fully analytical treatment of the entanglement dynamics for an isolated system of coupled oscillators following a sudden quench of the system parameters…
Predictive modeling of solidification during laser additive manufacturing of nickel superalloys: Recent developments, future directions
Supriyo Ghosh
Additive manufacturing (AM) processes produce parts with improved physical, chemical, and mechanical properties compared to conventional manufacturing processes. In AM processes, i…
Simulation and analysis of -Ni cellular growth during laser powder deposition of Ni-based superalloys
Supriyo Ghosh, Nana Ofori-Opoku, Jonathan E. Guyer
Cellular or dendritic microstructures that result as a function of additive manufacturing solidification conditions in a Ni-based melt pool are simulated in the present work using…
Particles with selective wetting affect spinodal decomposition microstructures
Supriyo Ghosh, Arnab Mukherjee, T. A. Abinandanan +1
We have used mesoscale simulations to study the effect of immobile particles on microstructure formation during spinodal decomposition in ternary mixtures such as polymer blends. S…
On the primary spacing and microsegregation of cellular dendrites in laser deposited Ni-Nb alloys
Supriyo Ghosh, Li Ma, Nana Ofori-Opoku +1
In this study, an alloy phase-field model is used to simulate solidification microstructures at different locations within a solidified molten pool. The temperature gradient an…
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…
Effects of particles on spinodal decomposition: A Phase field study
Supriyo Ghosh
In this thesis, we study the interplay of phase separation and wetting in multicomponent systems. For this purpose, we have examined the phase separation pattern of a binary mixtur…
