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 ...
Influence of Surface Topography and Tribosystem on Reciprocating Friction in Sparsely Lubricated Contacts
Surface texturing to achieve reduced sliding friction has been a widely studied topic, as seen in contemporary literature. Laser surface texturing, grinding and ion beam milling are popular techniques accepted by researchers ...
Engineering Bioactive Polymer/Ceramic Composite Nanofibrous Scaffolds for Bone Tissue Regeneration
Tissue repair and regeneration is a natural healing process seen in human body in response to injuries and infections. The regenerative capacity of most tissues decelerates with age and its associated pathological conditions. ...
Microstructure and mechanical properties of a 3D printed titanium alloy
The selective laser melting (SLM) process is increasingly being adopted for the manufacturing of metal parts as it provides better design flexibility and has the capability to produce near net shape complex parts, which ...
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 ...
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 ...
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 ...
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 ...
Role of in-phase octahedral tilt influencing structure and properties in Na0.5Bi0.5TiO3 - based piezoceramics
High performance perovskite (ABO3) based piezoceramics are used as actuators, pressure sensors, and transducers in wide-ranging applications spanning sectors like health, space, defence and automobiles. For over four ...
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 ...
