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 ...
Semisolid Die Casting of Wrought A6061 Aluminium Alloy
(2018-04-02)
The mechanical properties achieved with high performance wrought aluminium alloys are
superior to cast aluminum alloys. To obtain an intricate shaped component, wrought alloys are commonly subjected to forging followed by ...
A Study Of Crystallographic Texture, Residual Stresses And Mechanical Property Anisotropy In Aluminium Alloys For Space Applications
(2013-05-21)
Aluminium alloys, which are the most widely used materials in the aircraft and aerospace industries, find their applications due to high strength–to-density ratio, resistance to catastrophic fracture, high degree of ...
Microstructure Evolution In Semisolid Processing
(2014-09-09)
In this thesis, we present an experimental and numerical study of globularization during reheating of thixocast billet having non-dendritic microstructure. The process of reheating is an important step in the semisolid ...
Creep, Wear And Corrosion Behaviour Of Novel Magnesium Alloys And Composites
(2011-04-01)
In the present investigation, MMCs have been fabricated using the creep-resistant AE42 magnesium alloy as matrix and reinforcing it with saffil short fibres (essentially δ-Al2O2) and SiC particles in various combinations. ...
Effect Of Atomic Mobility In The Precipitate Phase On Coarsening : A Phase Field Study
(2010-10-28)
In this thesis, we have used a phase field model for studying the effect of atomic mobility inside the precipitate phase on coarsening behaviour in two dimensional (2D) systems. In all the available coarsening theories, ...
Evolution Of Texture And MIcrostructure During Processing Of Pure Magnesium And The Magnesium Alloy AM30
(2011-07-01)
Magnesium is the lightest metal that can be used for structural applications. For the reasons of weight saving, there has been an increasing demand for magnesium from the automotive industry. However, poor formability at ...
Role Of Boron On The Evolution Of Microstructure And Texture In Ti-6AL-4V-0.1B Alloy
(2013-06-04)
Titanium and its alloys constitute an important class of materials for aerospace, biomedical, and chemical industries, primarily due to their high specific strength and fracture toughness with good corrosion resistance. ...
Microstructure And Mechanical Properties Of Consolidated Magnesium Chips
(2013-04-04)
Development of sustainable manufacturing and conservation of primary materials are the key challenges to environmental degradation and climate change. Recycling of primary materials is one of the approaches suggested for ...
Studies On The Isolation And Characterisation Of Bioreagents For The Flotation Of Sphalerite From Galena-Sphalerite System
(2015-01-07)
A gradual depletion of high-grade ores, coupled with the growing demand for mineral commodities across the world has culminated in the increased exploitation of lean-grade ores with complex mineralogy. The mineral processing ...
