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…
Electrical Stressing Induced Monolayer Vacancy Island Growth on TiSe2
Husong Zheng, Salvador Valtierra, Nana Ofori-Opoku +5
To ensure the practical application of atomically thin transition metal dichalcogenides, it is essential to characterize their structural stability under external stimuli such as e…
