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 ...
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 ...
Lanthanide Photoluminescence: A Tool for Analyzing Local Heterogeneity in Ferroelectrics and Scope for High Performance Optical Thermometry
Rare-earth doped phosphors are fascinating both from scientific and technological standpoints because of the great scope it offers for spectral tuning, enabling a large variety of applications: from simple road markers to ...
Evolution of plasma electrolytic oxidation coatings formed on AM50 Mg alloy utilizing various alkaline electrolytes with and without glycerol additive and its corrosion behavior
The widespread application for Mg and its alloys are severely restricted mainly due to its relatively low strength and ductility and poor corrosion behaviour, particularly in the aqueous environment. The plasma electrolytic ...
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 ...
