Evolution of Microstructure and Texture in Manganese Steels
Twinning Induced Plasticity (TWIP) and Transformation Induced Plasticity (TRIP) steels possess excellent combination of high strength and high ductility. Deformation twinning and strain induced martensitic phase transformation ...
Novel Phenomena Associated With Giant Tetragonality in the Ferroelectric BiFeO3-PbTiO3 System
The multiferroic perovskite solid solution xBiFeO3-(1-x)PbTiO3 (BF-PT) exhibits very unique features such as giant tetragonality (c/a ~ 1.19), coexistence of ferroelectric and magnetic order (in certain composition range) ...
Development and Characterization of Ordered Magnetic Nanocomposite
Magnetic nano-particles dispersed in a non-magnetic matrix is promising for storage technology. Additionally, such magnetic nano composite (MNC) materials have potential applications in the field of telecommunication, ...
TEM Characterization of Microstructural Evolution of GaN Grown by MOCVD on c-Sapphire
III-Nitrides (AlN, GaN, InN) find use in the high-power high frequency applications. Bulk GaN substrates are difficult to grow, therefore the GaN based structures must be grown on foreign substrates.
In this thesis, ...
Effect of microstructure and texture on the dwell fatigue behaviour of titanium alloys
Ever since the failure of the fan blades of the Rolls Royce gas turbine engine that powered the Lockheed Martin tristar aircraft in 1972, ambient temperature dwell fatigue (DF) in titanium alloys has received considerable ...
Microbially-induced Mineral Flocculation and Flotation with Proteins and Polysaccharides Isolated from Paenibacillus
The most significant environmental issue that has arisen in the mining industries over the last decade is that of acid mine drainage (AMD) from tailing dumps and waste mined rock piles. AMD is caused by the oxidation of ...
Microstructure and Electrochemical Properties of Electrodeposited High Entropy Alloys Coatings
High entropy alloys (HEA) are composed of five or more alloying elements in a nearly equi-atomic ratio. HEAs exhibit high oxidation and corrosion resistance behaviour. In this work, HEA coatings were electrodeposited over ...
Architecting and Developing Sensors for Environmental Monitoring
Pollution arising from inorganic and organic contaminants is a major environmental hazard that needs imperative attention. Anthropogenic and natural deposition of heavy metal ions constitute a significant component of this ...
Synthesis and Phase Transformation Studies of Al45Mn55 Ferromagnetic Heusler Alloy
The aim of the present thesis work was to synthesize and explore the phase transformation behavior of a binary Heusler alloy based on AlMn system. The intermetallic phase with the stoichiometry AlMn, which is usually termed ...
