We work on different aspects of diffusion-controlled growth of the phases and microstructural evolution in complex multicomponent materials.

Recently, we solved the unsolved by developing new experimental methods in multicomponent diffusion. After nine decades, these remove the stringent mathematical and experimental obstacles associated with the equations established based on the Onsager formalism. These are being used in various multicomponent systems such as Nickel and Cobalt-based superalloys, complex concentrated (High Entropy) alloys and high temperature coatings in jet engines and power sectors. We are also developing the methods of high throughput combinatorial screening for the discovery of new materials with superior physical and mechanical properties.
