In a series of publications, the research group, led by Professor Chattopadhyay has discovered a new class of cobalt based superalloys that are free of tungsten. These alloys having ordered γ’ precipitates in fcc matrix exhibit much higher yield strength both at room temperature and high temperatures (upto 900°C) compared to existing cobalt based superalloys and have potential to compete with nickel based superalloys. Being tungsten free alloys, these newly developed alloys have lower density and possess higher specific strength. Read more

High temperature corrosion involves complex phenomenon, which broadly depends on chemistry of materials and its interacting environment. Measuring, analysing and diagnosing the high temperature corrosion issues are the major task performed by our group. Read more

The light alloys (Aluminum and Magnesium) constitute a major chunk of metal consumption world over due to their overwhelming use in civilian aircraft industry. We are looking into pushing the upper service temperature of such aluminum alloys by various routes such as composition control, microstructure tailoring, novel processing routes etc.

An exciting field, the quest for renewable and clean energy attracts a lot of attention world over. Like any other field, the theoretical frameworks developed over time need to be realized in practice and that is where the materials capabilities decide the practically achievable limits of these systems.

We have initiated efforts in a new programme looking for self cleaning coatings for solar applications and printable elctronics.

Additionally we have another programme where we are working on nano structured thermo electric materials for high temperature applications.
