In situ XRD studies of the process dynamics during annealing in cold rolled copper
S. Dey, N. Gayathri, M. Bhattacharya +1
The dynamics of the release of stored energy during annealing along two different crystallographic planes i.e.{111} and {220} in deformed copper have been investigated using in-sit…
Modality of Equilibration in Non-equilibrium Systems
P. Barat, A. Giri, Nilangshu K. Das +2
An open question in the field of non-equilibrium statistical physics is whether there exists a unique way through which non-equilibrium systems equilibrate irrespective of how far…
Statistics of dislocation pinning at localized obstacles
A. Dutta, M. Bhattacharya, P. Barat
Pinning of dislocations at nanosized obstacles like precipitates, voids and bubbles, is a crucial mechanism in the context of phenomena like hardening and creep. The interaction be…
Universal Scaling Property of System Approaching Equilibrium
P. Barat, A. Giri, M. Bhattacharya +2
In this Letter we show that the diffusion kinetics of kinetic energy among the atoms in non- equilibrium crystalline systems follows universal scaling relation and obey Levy-walk p…
Quasistatic Stick-slip in Dislocation Core and Frenkel-Kontorova Chain
M. Bhattacharya, A. Dutta, P. Barat
By means of atomistic simulations, we demonstrate that a dislocation core exhibits intermittent quasistatic restructuring during incremental shear within the same Peierls valley. T…
Mechanism of Climb in Dislocation-Nanovoid Interaction
A. Dutta, M. Bhattacharya, N. Gayathri +2
We employ the methods of atomistic simulation to investigate the climb of edge dislocation at nanovoids by analyzing the energetics of the underlying mechanism. A novel simulation…
