Influence of morphological instability on grain boundary trajectory during directional solidification
Supriyo Ghosh, Alain Karma, Mathis Plapp +3
The interplay between the diffusion-controlled dynamics of a solidification front and the trajectory of a grain boundary groove at the solid-liquid interface is studied by means of…
Simulation of temperature, stress and microstructure fields during laser deposition of Ti-6Al-4V
Supriyo Ghosh, Kevin McReynolds, Jonathan E. Guyer +1
We study the evolution of prior columnar phase, interface phase, and phase during directional solidification of a Ti-6Al-4V melt pool. Finite element simulations estima…
High-throughput assessment of vacancy formation and surface energies of materials using classical force-fields
Kamal Choudhary, Adam J. Biacchi, Supriyo Ghosh +3
In this work, we present an open access database for surface and vacancy-formation energies using classical force-fields (FFs). These quantities are essential in understanding diff…
On the Interfacial Phase Growth and Vacancy Evolution during Accelerated Electromigration in Cu/Sn/Cu Microjoints
Vahid Attari, Supriyo Ghosh, Thien Duong +1
In this work, we integrate different computational tools based on multi-phase-field simulations to account for the evolution of morphologies and crystallographic defects of Cu/Sn/C…
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…
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…
