Phase Field Benchmark Problems for Dendritic Growth and Linear Elasticity
Andrea M. Jokisaari, Peter W. Voorhees, Jonathan E. Guyer +2
We present the second set of benchmark problems for phase field models that are being jointly developed by the Center for Hierarchical Materials Design (CHiMaD) and the National In…
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…
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…
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…
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…
