Research Areas:

I am a dedicated researcher on physical and mechanical metallurgy of Steel and my interest areas can be classified into the following broad categories:
(1) Development of microstructure and texture in steel during thermo-mechanical processing.
(2) Studying the effect of microstructure and texture on mechanical properties of steel: especially ductile-to-brittle transition behaviour and low-temperature toughness.
(3) Development of steel grades having high strength and high toughness.
(4) Characterization of macro- and micro-segregation in continuous cast slab and studying their effect on slab-reheating, rolling and final mechanical properties.
(5) Developing novel grain structures in low-carbon (ferritic) steels, such as, ultra-fine grain structure or bimodal grain structures, and evaluating their effect on the mechanical properties (primarily tensile properties and toughness).
(6) Understanding the role of so-called harmful inclusions, such as, TiN and MnS and precipitates in generating ductile and brittle fracture in steel and improving the mechanical properties in spite of the presence of large inclusions, by controlling the microstructure (through careful processing and heat-treatment).
(7) Studying the formation of various microalloy precipitates, such as, Nb(C,N), V(C,N), (Ti, Mo)C during hot-rolling, thermo-mechanical controlled rolling and also cold-rolling and annealing treatments of HSLA steels and evaluating the effect of those precipitates on the microstructure, texture and mechanical properties.
(8) Defect initiation and its control in metals and alloys.
