Finite Interface Dissipation Phase Field Modeling of Ni-Nb under Additive Manufacturing Conditions
Kubra Karayagiz, Luke Johnson, Raiyan Seede +8
During the laser powder bed fusion (L-PBF) process, the built part undergoes multiple rapid heating-cooling cycles, leading to complex microstructures with nonuniform properties. I…
Exact relaxation dynamics and quantum information scrambling in multiply quenched harmonic chains
Supriyo Ghosh, Kumar S. Gupta, Shashi C. L. Srivastava
The quantum dynamics of isolated systems under quench condition exhibits a variety of interesting features depending on the integrable/chaotic nature of system. We study the exact…
Spectral Calibration of KM Giants from medium resolution near-infrared HK-band spectra
Supriyo Ghosh, Soumen Mondal, Ramkrishna Das +1
We present here new medium resolution spectra ( 1200) of KM giants covering wavelength range 1.501.80 and 1.952.45 m. The sample includes 72 K0M8 giants…
Uncertainty Analysis of Microsegregation during Laser Powder Bed Fusion
Supriyo Ghosh, Mohamad Mahmoudi, Luke Johnson +3
Quality control in additive manufacturing can be achieved through variation control of the quantity of interest (QoI). We choose in this work the microstructural microsegregation t…
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…
