General Information: 

In brief, our research in “Novel Alloys Design and Development Laboratory” has been mainly focused on design, development and analysis of multicomponent intermetallic and metallic glass alloy systems which include nanoalloys, bulk amorphous and bulk nanocrystalline alloy systems. These studies are mostly supplemented with modeling and simulations to reveal atomistic mechanisms governing structure-property-performance relationships for alloys in consideration.

Our computational tools involve several workstations with first-principle calculation softwares such as abinit and Medea-Vasp, Molecular Dynamics and Monte Carlo packages and in-house electronic calculation, simulation and data analyses algorithms. Our group has a solid background in theoretical investigations of order-disorder and related phenomena in binary and ternary alloy systems. With our computational capabilities, we intend to compare/contrast such phenomena under finite surface conditions of nanoalloy forms also.
