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…
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…
Anisotropy in interface stress at the BCC-iron solid-melt interface: molecular dynamics and phase field crystal modelling
Sushil Kumar, Ming-Wei Liu, Kuo-An Wu +1
The interface stresses at of the solid-melt interface are, in general, anisotropic. The anisotropy in the interfacial stress can be evaluated using molecular dynamics (MD) and phas…
Finite temperature electronic structure of Diamond and Silicon
Vaishali Shah, Bhavik Sanghavi, Rahul Ramchandani +2
The electron-phonon interaction contribution to the electronic energies is included in density functional total energy calculations with ab initio pseudopotentials via the Allen fo…
Phase field modelling of precipitate morphologies in systems with tetragonal interfacial free energy anisotropy
Arijit Roy, M P Gururajan
A wide variety of morphologies arise due to the tetragonal anisotropy in interfacial free energy. In this paper, we report on a family of Extended Cahn-Hilliard (ECH) models for in…
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…
