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…
Anomalous interaction between dislocations and ultra-small voids
A. Dutta, M. Bhattacharya, P. Mukherjee +3
We carry out the molecular statics simulations of depinning of an edge dislocation at voids of diameters of the order of ~1 nm. We show that the dislocation-void interactions are n…
Inertial Oscillations of Pinned Dislocations
M. Bhattacharya, A. Dutta, P. Mukherjee +2
Dislocation pinning plays a vital role in the plastic behaviour of a crystalline solid. Here we report the first observation of the damped oscillations of a mobile dislocation afte…
Dislocation in Motion as the Dynamic Distribution of Elastic Field Singularity
A. Dutta, M. Bhattacharya, P. Mukherjee +3
Plastic deformation of crystals is a physical phenomenon, which has immensely driven the development of human civilisation since the onset of the Chalcolithic period. This process…
Lattice Resistance to Dislocation Motion : Singularity Distribution Approach
A. Dutta, M. Bhattacharya, P. Mukherjee +3
This paper has been withdrawn.
Lattice Resistance to Dislocation Motion at the Nanoscale
A. Dutta, M. Bhattacharya, P. Barat +3
In this letter we propose a model that demonstrates the effect of free surface on the lattice resistance experienced by a moving dislocation in nanodimensional systems. This effect…
