Effect of Cr Segregation on Grain Growth in Nanocrystalline α-Fe Alloy: A Multiscale Modelling Approach
Sandip Guin, Albert Linda, Yu-Chieh Lo +2
We present a multiscale modelling framework that integrates density functional theory (DFT) with a phase-field model (PFM) to explore the intricate dynamics of grain growth in nano…

Interplay between thermal and compositional gradients decides the microstructure during thermomigration: a phase-field study
Sandip Guin, Soumya Bandyopadhyay, Saswata Bhattacharyya +1
The presence of thermal gradients in alloys often leads to non-uniformity in concentration profiles, which can induce the thermomigration of microstructural features such as precip…

Solute Segregation in a Moving Grain Boundary: A Novel Phase-Field Approach
Sandip Guin, Miral Verma, Soumya Bandyopadhyay +2
We present a novel phase-field approach for investigating solute segregation in a moving grain boundary. In our model, the correct choice of various parameters can control the solu…
