We present a general approach for determining the equilibrium shape of isolated, coherent, misfitting particles by minimizing the sum of elastic and interfacial energies using a synthesis of finite element and optimization ...

The aim of the present work is to engineer a new kind of coating material with superior quality and reliability in a cost effective way by laser cladding and ball milling process. Non equilibrium processing methods were ...

The aim of the present thesis work was to synthesize and explore the phase transformation behavior of a binary Heusler alloy based on AlMn system. The intermetallic phase with the stoichiometry AlMn, which is usually termed ...

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 ...

III-Nitrides (AlN, GaN, InN) find use in the high-power high frequency applications. Bulk GaN substrates are difficult to grow, therefore the GaN based structures must be grown on foreign substrates. In this thesis, ...

Background and Objective: Nickel-base superalloys, strengthened by a high volume fraction of Ni3Al precipitates, have been the undisputed choice for turbine discs in gas turbines as they exhibit the best available combination ...

Thermal barrier coating systems (TBC’s) employed in the high pressure turbine section of a modern aero-turbine engine serve as an example of constrained material systems used for engineering applications. TBC’s today are ...

The past few years have witnessed significant work being directed towards drug delivery systems with layer-by layer (LbL) technique prominently featured as one of the most sought after approach. However, majority of the ...
