Effect of Length Scale on High Temperature Mechanical Behavior of Sn-Cu Joints: A Mechanics and Material Science Based Treatment
With the ongoing miniaturization of microelectronic devices, the size of compliant solder in microscale solder joints has significantly reduced, proportion of brittle phases has increased, and the microscale joints have ...
An Evaluation of the Mechanical Behavior of some new High Temperature Materials
Two new high-temperature alloy systems have been discovered recently at the Indian
Institute of Science, which form the basis of this thesis. The first alloy system is an
Intermetallic-Intermetallic eutectic composite ...
Thermo-Mechanical Processing of Third Generation γ – Titanium Aluminides
The γ – TiAl based intermetallics are characterized by unique combination of the properties which
make these materials amenable for the application in gas turbines. However, due to problems
related to limited plasticity ...
Co-continuous microstructures through spinodal decomposition in ternary systems: A phase field study
We have studied spinodal decomposition which leads to a three-phase microstructure in ternary
alloys using computer simulations based on the ternary Cahn-Hilliard equations. All the alloys
we have studied are in the same ...
Development of wrought Mg-Li based alloys with improved strength and ductility
A comprehensive investigation has been undertaken to develop cold rolled Mg-Li based alloys with tensile properties superior to the existing commercial or experimental Mg-Li based alloys. In this endeavor, melting and ...
On the development of Fe-containing high entropy alloys with improved strength at high temperatures
The emergence of new multicomponent high entropy alloys (HEA) has opened up new avenues for development of high performance materials for structural applications [1]. Among all of them, the precipitation strengthened HEAs ...
On the creep behaviour of Ni based solid solution alloys from binary to quaternary
On the creep behavior of Ni based solid solution alloys from binary to quaternary
A power-law relationship between the steady state strain rate (𝜀̇) and imposed stress (σ) is well established so that the 𝜀̇∝𝜎^𝑛, at a ...
