On the development of low mass density gamma strengthened Co-based superalloys
The work herein aims at developing new class of low mass density gamma-strengthened Co-based
superalloys with good solvus temperature through systematic addition of Cr into the Co-Ni-Al-
Mo-Ta based superalloy. The present ...
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, ...
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 ...
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. ...
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 ...
Numerical and experimental investigation of Process-Structure-Property relationship in Organic Photovoltaics
Organic Photovoltaics (OPVs) are considered to be potential contenders amongst the third-generation solar technologies. The primary reason for their popularity has been the possibility of applying various cost-effective ...
Microstructure and Shape Memory Behavior of quaternary Ni(50-x)-(Pt/Pd)x-Ti(50-y)-(Hf/Zr)y alloys
Shape memory alloys (SMA) are those class of alloys that can cause shape memory, pseudoelastcity and two-way memory effects due to reversible austenite to martensite phase transformations. The NiTi shape memory alloys ...
Development of a low modulus Ti-Nb-Ta-O alloy for orthopedic applications
Ti-Nb-Ta-Zr based β-Titanium alloys are currently projected as potential candidates for use in orthopaedic implants owing to their low elastic modulus and use of non-toxic elements. However, most of these alloys contain ...
Improvement of High Temperature Oxidation Behavior of ‘w’ Free Y strengthened Co-based Superalloys through Alloying Addition
The discovery of coherent g-g’ microstructure in Co-Al-W and Co-Al-Mo-Nb/Ta systems represents new possibilities for turbine engines materials. Their chemical and mechanical properties are similar to commercially successful ...
Understanding the demixing behavior and structure-property correlation in graphene oxide containing LCST blends
A number of researchers have studied about the effects of different nanoparticles on the phase separation of LCST polymer blend systems. Many nanoparticles such as carbon nanotubes and silica have been incorporated in ...
