Densification Mechanisms for Spark Plasma Sintering in Alumina and Alumina Based Systems
(2018-03-19)
The densification mechanisms of polycrystalline α-alumina by spark plasma sintering are highly contradictory, with different research groups suggesting diffusion to dislocation controlled mechanisms to be rate controlling. ...
Some Critical Issues Pertaining To Deformation Texture In Close-Packed Metals And Alloys : The Effect Of Grain Size, Strain Rate And Second Phase
(2013-05-20)
Crystallographic texture in polycrystalline materials are known to play an important role in tailoring suitable properties for various technological applications. In addition, the evolution of texture provides a profound ...
Design & Fabrication of Bio-responsive Drug Carriers Based on Protamine & Chondroitin Sulphate Biopolymers
(2017-10-26)
The present thesis focuses on the fabrication of bio-stimuli responsive micro- and nano-carriers for drug delivery applications. In particular, the objective of this work is to investigate the possibility of using polypeptide ...
Fracture and Deformation in Bulk Metallic Glasses and Composites
(2018-01-11)
Plastic flow in bulk metallic glasses (BMGs) localizes into narrow bands, which, in the absence of a microstructure that could obstruct them, propagate unhindered under tensile loading. In constrained deformation conditions ...
Some Processing and Mechanical Behavior Related Issues in Ti-Ni Based Shape Memory Alloys
(2017-11-30)
Shape memory alloys (SMAs) exhibit unique combination of structural and functional properties and hence have a variety of current and potential applications. The mechanical behaviour of SMAs, in particular the influence ...
Effect of Li Addition on the Plasticity of AZ31 Mg-Alloy
(2017-11-14)
Mg-alloys, despite being the lightest structural metallic materials, find limited applications due to their poor workability, which is due to the hcp structure that does not provide sufficient number of independent slip ...
Destabilisation and Failure of Cylindrical Nanopores : A Phase Field Study
(2017-11-28)
Phase field models have played an important role in shaping our understanding of a variety of micro structural phenomena in materials. Their attractive features include (a) their ability to capture instabilities in ...
Magnesium Matrix-Nano Ceramic Composites By In-situ Pyrolysis Of Organic Precursors In A Liquid Melt
(2013-06-20)
In this thesis, a novel in-situ method for incorporating nanoscale ceramic particles into metal has been developed. The ceramic phase is introduced as an organic-polymer precursor that pyrolyzes in-situ to produce a ceramic ...
Investigations On The Properties Of TiN, NbN Thin Films And Multilayers By Reactive Pulsed Laser Deposition
(2013-10-21)
Two technologies, namely Laser Technology and Surface Modification Technology, have made rapid strides in the last few decades. The lasers have evolved from a simple laboratory curiosity to a matured industrial tool and ...
Fatigue Damage Characterization Of Carbon/Epoxy Laminates Under Spectrum Loading
(2013-10-04)
