Multi-Scale Approaches For Understanding Deformation And Fracture Mechanisms In Amorphous Alloys
(2010-03-09)
Amorphous alloys possess attractive combinations of mechanical properties (high elastic limit, ~2%, high fracture toughness, 20-50 MPa.m1/2, etc.) and exhibit mechanical behavior that is different, in many ways, from that ...

(2016-04-26)
Giant magnetostrictive RFe2 type (R represents rare earths) intermetallics form an important class of magnetic materials keeping in view of their potential applications as sensors and/ or actuators. In this thesis, one ...
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 ...
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 ...
