Dr. Mandal and his research team are involved in designing new alloys with improved mechanical and corrosion properties. Further, his group is also involved in improving the material properties and performance of the existing alloys employing microstructure engineering approach. They have undertaken a systematic campaign to understand, evaluate and establish the various grain boundary related specific materials properties as a function of five microscopic degrees of freedom of boundaries for a range of bulk polycrystalline materials. Materials properties are being improved by understanding the synergistic influence of various microstructural features like grain boundary character, grain boundary morphology, micro-texture, grain size, precipitate morphology and its distribution etc. A systems and optimisation approach has been undertaken whereby certain property packages, rather than just a single property is achieved through this new strategy to microstructure engineering.
