深Choudhuri博士

Currently, we are focussed on: (1) underst和ing the crystallography, energetics, kinetics of phase transformations in solid 和 液态s of metallic 合金; 和, (2) examining defect formation 和 propagation in crystalline 材料.  我们最近的 研究结果如下:

通过耦合 从头开始 Molecular Dynamics 和 unsupervised learning algorithms, we have discovered two transformation pathways during the solidification of binary Al-Sc allloys: (i)$\mathrm{Sc}-centere\mathrm{d-}polyhedrons\to L12-{\mathrm{Al}}_3\mathrm{Sc}\to liquid-Al/L12-Al3Sc-interfacia\mathrm{l-}ordering\to fcc-\mathrm{Al}$; 和 (ii) $\mathrm{Sc}-centere\mathrm{d-}polyhedrons\to hcp-\mathrm{Al}\to bcc-\mathrm{Al}\to fcc-\mathrm{Al}$. These pathways open doors for engineering alloy solidification - starting from the 液态.(物理评论材料, 6(10), p.103406)

Our classical MD simulations have uncovered non-classical nucleation mechanisms during 镍铬合金的结晶. 这种机制解释了为什么要集中 Ni-Cr solidifies into multiphase microstructures.(Scripta Materialia, 199, p.113857)
