The main research interestes of our group are developing porous and hybrid materials using powder metallurgy and casting routes and analyze their microstructure - properties correlations. At present our main focus areas are as follows:
- Processing of porous ceramic materials with tailorable pore morphologies and pore volume fractions using different powder metallurgical routes
- Processing of metal/ceramic composite materials having interpenetrating structure and with a wide range of phase architectures to develop custom made composite materials consisting of different metallic alloy and ceramic combinations
- Non-destructive analysis of the structure and properties of the developed porous and composite materials, which include micro computer tomography to perform three dimensional bulk structural analysis, ultrasonic phase spectroscopy to determine the complete stiffness tensor of complex non-isotropic materials etc.
- Mechanical and thermal property analysis of hybrid materials at room and elevated temperatures to develop microstructure - property correlations
- Stress analysis in composite materials using energy dispersive synchrotron radiation to study the processing induced residual stresses as well as the mechanism and extent of load transfer from one phase to another
