Role Of Solid Phase Movement And Remelting On Macrosegregation And Microstructure Formation In Solidificaiton Processing
(2010-08-25)
Melt convection and solid phase movement play an important role in solidification processes, which significantly influence the formation of grain structures and solute segregations. In general, the melt convection and grain ...
Studies On Transport Phenomena During Solidification In Presence Of Electromagnetic Stirring
(2010-07-20)
In several applications of casting, dendritic microstructure is not desirable as it results in poor mechanical properties. Enhancing the fluid flow in the mushy zone by stirring is one of the means to suppress this dendritic ...
Effect Of Free-Volume On The Fracture And Fatigue Of Amorphous Alloys
(2010-07-01)
Bulk metallic glasses (BMGs) are a new class of structural materials and exhibit unique combinations of mechanical properties. As a result, their mechanical behavior has been an active area of scientific pursuit in the ...
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. ...
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, ...
