Dislocation assisted coarsening of coherent precipitates: a phase field study
Arjun Varma R, Prita Pant, M P Gururajan
Coarsening of precipitates in coherent systems is influenced by the elastic fields of the precipitates and the interfacial curvature. It is also known that if precipitates are conn…
Stacking fault energy induced softening in the nucleation limited plasticity regime: a molecular dynamics study on Cu-Al alloys
G Kamalakshi, Prita Pant, M P Gururajan
In general, with the addition of solutes, the yield strength of alloys is expected to increase and this phenomenon is known as solid solution strengthening. However, reports on the…
Physical phenomena during nanoindentation deformation of amorphous glassy polymers
Prakash Sarkar, Prita Pant, Hemant Nanavati
We identify for visco-elasto-plastic (VEP) glassy polymers, physical phenomena during Berkovich nanoindentation, a locally imposed deformation. Live visuals via in situ nanoindenta…
Probing thermal expansion of graphene and modal dispersion at low-temperature using graphene NEMS resonators
Vibhor Singh, Shamashis Sengupta, Hari S. Solanki +5
We use suspended graphene electromechanical resonators to study the variation of resonant frequency as a function of temperature. Measuring the change in frequency resulting from a…
Dislocation assisted phase separation: a phase field study
Arjun Varma R, Prita Pant, M P Gururajan
Defects play a key role in deciding the mechanisms and kinetics of phase transformations. In this paper, we show how dislocations influence phase separation in alloys with miscibil…
Effect of stacking fault energy on nucleation limited plasticity in Cu-Al alloys
G. Kamalakshi, Prachi Limaye, M. P. Gururajan +1
We study the effect of Stacking Fault Energy (SFE) on the deformation behaviour of copper and copper-aluminium alloys using Molecular Dynamics (MD) simulation. We find that both yi…
