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 ... -
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. ... -
Study Of Gas-Liquid Flow Behaviour In Raceway Zone Under Pulverised Coal Injection
(2011-02-09)Gas, liquid and powder flow in the lower part of a blast furnace is complex phenomena. In order to understand the aerodynamics of the blast furnace properly, these phenomena must be included in their advanced form. Previous ... -
Grain Boundary Processes In High Temperature Densification And Deformation Of Nanocrystalline Zirconia
(2011-02-08)Grain boundary processes play a major role in controlling different rate processes in yttria stabilized tetragonal zirconia. The present study concentrated on rate processes in tetragonal zirconia, which were significantly ... -
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, ... -
Reactive Hot Pressing Of ZrB2-Based Ultra High Temperature Ceramic Composites
(2010-10-08)Zirconium- and titanium- based compounds (borides, carbides and nitrides) are of importance because of their attractive properties including: high melting temperature, high-temperature strength, high hardness, high elastic ... -
Study Of Evaluation Of Texture And Microstructure During Different Modes Of Rolling And Annealing Of Two Phase α-β Brass
(2010-09-28)It is well known that texture and microstructure play a crucial role in determining properties of metallic materials. The evolution of microstructure and texture during deformation and annealing of copper and some copper ... -

Processing Of Zirconia Based Honeycombs And Evaluation Of Thermo Mechanical Properties
(2010-08-16)Ceramic cellular solids, mainly honeycombs and foams, are a novel class of composite materials where one phase is an interconnected network of solid struts or plates and the other one an empty phase or possibly a fluid. ... -
First Principles Study Of Structure And Stacking Fault Energies In Some Metallic Systems
(2010-08-05)Plastic deformation in crystalline materials largely depends on the properties of dislocations, in particular their mobility. While continuum description of deformation of a crystalline metal can be made reasonably well ... -
