Effect of thermo-mechanical treatment on the evolution of microstructure and mechanical properties in a β and a β rich α+β titanium alloy
Near β and metastable β-titanium alloys are difficult to process due to narrow processing window. Lower processing temperature causes difficulty in recrystallization of these alloys especially in the two phase conditions, ...
Architecting Conjugated Molecules for Band Gap Engineering & Photostability
Organic photovoltaic (OPV) modules are flexible, light weight, transparent and thin compared to other emerging photovoltaic technologies, making them well-suited for applications ranging from solar windows to fabrics. A ...
Electromagnetic interference shielding materials derived from epoxy based nanocomposites
The thesis entitled “EMI shielding materials derived from epoxy based
nanocomposites” systematically studies the effect of CF and surface modified CF on the
EMI shielding of epoxy composites. In addition, to target the ...
Evaluation of Low-stress High-temperature Creep: Insights into the Harper-dorn Creep
The theory of creep behavior of single crystals and polycrystalline materials having large grains at very low-stresses and at very high temperatures, as originally proposed by Harper and Dorn in 1957, has been under constant ...
Synthesis, Microstructural Stability and High Temperature Deformation of Alumina-Carbon Nanotube Composites
Structural ceramics such as alumina are known to have excellent hardness and high
temperature mechanical properties. In view of this, they are used as refractory linings to mitigate
the effect of high temperature exposure. ...
Effect of High-Pressure Torsion and Natural Ageing on Hardness, Electrical Resistivity and Fatigue Properties of Commercially Pure Cu
Commercially pure Cu was processed through high-pressure torsion (HPT) at a pressure of 6 GPa starting from ¼ up to 50 turns. These samples were then naturally aged for 1.75 years under the laboratory condition. Subsequently, ...
Evaluation of Power-Law Creep in Bending
Materials for engineering components operating at high temperatures during their service like rockets, aero-turbines, automobile engines, nuclear power plants, steam power plants and micro-electronics are often designed ...
Nano-mechanical, optical and structural property correlations in binary, ternary, and quaternary tellurium-based chalcogenide glasses
Over a half century, from the advent of chalcogenide glasses, it was used for various applications like xerography, phase change memories (PCM), solar cells, infrared devices and so on. These applications made use of some ...
Polymer-based investigations into the surface chemistry of some sulphide minerals and the beneficiation of a low grade siliceous copper ore
Tanzania is endowed with rich mineral deposits containing gold, tanzanite, diamond, coal, uranium, iron ore, gemstones with low grade of the sulphide minerals namely chalcopyrite and pyrite. It is the third largest producer ...
Studies on Internal Reforming Solid Oxide Fuel Cell
Renewable energy becomes inevitable for future energy needs. Accordingly, researchers are exploring possible alternatives to conventional fuel based internal combustion engines. In recent years, Bio-fuel (methane/ethanol) ...
