Research Statement and Highlights:
Advanced materials with high strength and toughness are in great demand because they can be used to make structural components lighter and more energy (and fuel) efficient. The research in my group is focused on the development of a new class of engineering materials with high strength, toughness and ductility.
Advanced Structural Steels:
We are developing materials (Bainitic steels, Austempered Ductile Iron) with exceptional combination of yield strength, fracture toughness and fatigue resistance. We have focused on novel materials processing which results in extremely fine grain microstructure and with a combination of several phases i.e. ductile and highly deformable phase e.g. ferrite and a strong and highly resistant to fracture (austenite) phase with high carbon content. Using a combination of unique thermo mechanical treatment and phase transformations, such microstructures are developed in bainitic steels and austempered ductile cast irons.
Superconducting Thin Films:
Superconducting thin films can reduce overall energy consumption and transmission losses. Another major Research activity in my group is development of super-conducting thin films by electroless deposition.
In recent years there has been a significant interest in carbon nano tubes as engineering materials because of their unique physical and mechanical properties. Another focus of our research is on developing Carbon Nanotube reinforced and metal matrix polymer composites.
Other Research Activities:
- Development of a new class of austenitic structural steels and magnetic materials
- Stress corrosion cracking behavior of high strength steels
