Co-continuous microstructures through spinodal decomposition in ternary systems: A phase field study
We have studied spinodal decomposition which leads to a three-phase microstructure in ternary alloys using computer simulations based on the ternary Cahn-Hilliard equations. All the alloys we have studied are in the same ... -
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 ... -
Development of a wrought Mg‒7Sn‒3Zn alloy with improved strength and ductility
The current focus of research in Mg alloys is to develop wrought alloys suitable for the automotive industry. The challenges to be overcome are low strength, poor ductility, and high cost associated with wrought Mg‒based ... -
Effect of Sintering on Microstructure and Mechanical Properties of Air Plasma Sprayed 7 wt.% Y2O3 Stabilized ZrO2
Air plasma sprayed (APS) 7 wt.% Y2O3 stabilized ZrO2 (7YSZ) coating is conventionally used for thermal insulations (in form of thermal barrier coating, TBC) in various hotter sections of land-based gas turbine engines and ... -
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 ... -
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 ... -
Numerical Simulations on the Indentation Behaviour of Shape Memory Alloys
Shape Memory Alloys (SMAs) are increasingly being used as micro actuators, sensors, as self expanding cardiovascular stents and in MEMs based devices because of their ability to recover large values of imposed strain. ... -
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 ... -
Structure-Property correlation in epoxy composites containing carbonaceous nanoparticles
Epoxy is widely used as thermosetting materials in carbon fiber composites due to its combined superior thermal and mechanical properties which makes them a potential candidate for myriad applications. But epoxy suffers ... -
Thermo-Mechanical Processing of Third Generation γ – Titanium Aluminides
The γ – TiAl based intermetallics are characterized by unique combination of the properties which make these materials amenable for the application in gas turbines. However, due to problems related to limited plasticity ...
