Microstructure Design And Interfacial Effects On Thermoelectric Properties Of Bi-Sb-Te System
(2017-09-07)
Climate change is a subject of deep distress in today’s world. Over dependence on hydrocarbon has resulted in serious environmental problems. Rising sea level, global warming and ozone layer depletion are the mainstream ...
Synthesis and Phase Transformation Studies of Al45Mn55 Ferromagnetic Heusler Alloy
The aim of the present thesis work was to synthesize and explore the phase transformation behavior of a binary Heusler alloy based on AlMn system. The intermetallic phase with the stoichiometry AlMn, which is usually termed ...
Evolution Of Texture And Its Correlation With Microstructure And Mechanical Property Anisotropy In AA7010 Aluminum Alloy
(2016-07-12)
Al-Zn-Mg-Cu-Zr based AA7010 aluminum alloy belongs to the class of heat treatable alloys and the semi-finished products are generally produced by hot rolling, forging or extrusion processes. It is well known that the ...
Synthesis and Transformation of AuCu Intermetallic Nanoparticles
(2018-04-16)
Investigations on size dependent phase stability and transformations in isolated nanoparticles have gained momentum in recent times. Size dependent phase stability generates size specific particle microstructure which ...
Synthesis And Study Of Microstructure Evolution In Nanoparticles Of Immiscible Alloys By Laser Ablation Under Liquid Medium
(2017-05-21)
The present thesis deals with synthesis of free alloy nanoparticles in immiscible alloy systems by the process of laser ablation under a liquid. In this process the alloy target is submerged in a liquid and the plume formed ...
Microstructure Development During Laser And Electron Beam Welding Of Ti/Ni Dissimilar Joints
(2009-09-02)
Fusion welding of dissimilar metals constitutes a crucial processing stage in a variety of applications, and the use of high energy beams (HEB) like lasers and electron beams for such welding applications has several ...
Study Of Friction And Wear Behaviour Of Nano-Embedded Aluminium Alloys
(Indian Institute of Science, 2005-12-22)
In general, the bearing alloys have two types of microstructure i.e., either a soft matrix with discrete hard particles or a continuous matrix of the harder metal with small amount of the softer metal finely dispersed in ...
Studies On Synthesizing Fe And Fe-Cu Nanopowders By Levitational Gas Condensation Process And Their Consolidation Characteristics
(2015-02-25)
There exist large number of techniques for the preparation of nanostructured materials. Among them the preparation of nanopowders by gas/vapour condensation is a popular one. Because of very high level of surface to volume ...
