Understanding the Effect of Uniaxial Tensile Strain on the Early Stages of Sensitization in AISI 304 Austenitic Stainless Steel
P. S. Chowdhurya, S. K. Guchhait, P. K. Mitra +3
In the present study, an attempt has been made to understand the effect of different competing mechanisms controlling the overall degree of sensitization (DOS) of deformed austenit…
Magnetic hysteresis loop as a probe to distinguish single layer from many layer graphitic structure
K. Bagani, B. Ghosh, M. K. Ray +3
In this report we have pointed out that magnetic hysteresis loop can be used as a probe to distinguish a single layer from a many layer graphitic structure. Chemically we have synt…
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…
Temperature Dependence of the Dynamics of Portevin-Le Chatelier Effect in Al-2.5%Mg alloy
A. Chatterjee, K. L. Murty, N. Gayathri +2
Tensile tests were carried out by deforming polycrystalline samples of Al-2.5%Mg alloy at four different temperatures in an intermediate strain rate regime of 2x10-4s-1 to 2x10-3s-…
In situ studies of evolution of microstructure with temperature in heavily deformed Ti-modified austenitic stainless steel by X-ray Diffraction technique
P. S. Chowdhury, N. Gayathri, P. Mukherjee +4
The mechanism of the evolution of the deformed microstructure at the earliest stage of annealing where the existence of the lowest length scale substructure paves the way to the fo…
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…
