Microstructural, Mechanical and Oxidation Behavior of Ni-Al-Zr Ternary Alloys
(2018-01-09)
The thesis introduces a novel alloy system based on submicron distributions of intermetallic phases realised through eutectic solidification in the ternary system Ni-Al-Zr. Various compositions in this system comprising ...
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 ...
Eutectic microstructures: Role of interfacial energy anisotropy and diffusivities
Eutectic alloys find a wide application in industrial cast alloys, solder alloys, and in the emerging field of functional materials. Apart from technological applications, multiphase eutectic alloys have also received keen ...
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, ...
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 ...
On the development of Fe-containing high entropy alloys with improved strength at high temperatures
The emergence of new multicomponent high entropy alloys (HEA) has opened up new avenues for development of high performance materials for structural applications [1]. Among all of them, the precipitation strengthened HEAs ...
Investigation of thermoelectric properties of Sn-Te based alloys with microstructural studies
The basic concept of thermoelectricity is the conversion of dissipated heat into electricity with applications in the areas such as automobile engineering, refrigerating coolants, satellites, etc. The thermoelectric figure ...
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 ...
Structure-Property Correlation in Additively Manufactured High-Temperature Materials: Insights from Nickel-Based Superalloy IN718 & Nickel-Based Eutectic High Entropy Alloy AlCoCrFeNi2.1
High-temperature alloys are technically very important materials that possess higher resistance toward mechanical and chemical degradation at 0.4-0.6 TM for a constant/cyclic load. These attributes make them candidate ...
