Electrochemical Behavior of Metallic Coatings Containing Carbonaceous Additives
Coatings have been traditionally used for protection against corrosion. Therefore, substantial efforts have been focused on engineering the microstructure and morphology of coatings to enhance their corrosion resistance ...
Microstructure and texture evolution in wire drawing and its role on the tension and torsion response of nickel microwires
It is now well known that the strength of the metallic materials depends on microstructural features such as dislocation density, grain size, and precipitates. The migration of lattice defects such as dislocations is a ...
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 ...
Effect of off-stoichiometry, grain size and chemical substitution on microstructure, global structure, electromechanical and energy storage properties of lead free Na0.5Bi0.5TiO3 (NBT) based piezoceramics
Ferroelectric and piezoelectric materials, especially the polycrystalline ceramics, are promising candidates for application in pressure sensors, actuators, transducers, ultrasonic motors, energy storage capacitors, ...
Microstructure and texture engineering strategies to enhance the corrosion resistance of tin based coatings
Coating corrosion-prone material with metal/alloy and passivated oxide layers is the primary protection method in the ever-evolving corrosion protection area. To improve the corrosion resistance of the coatings, the coating ...
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 ...
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, ...
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 ...
