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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

The current focus of research in Mg alloys is to develop wrought alloys suitable for the automotive industry. The challenges to be overcome are low strength, poor ductility, and high cost associated with wrought Mg‒based ...

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 ...

Since the discovery of age hardening, a large number of alloys have been produced that exploit the presence of one or more precipitate phases in the microstructure for strength enhancement. In recent decades, alloys with ...
