Research Interests

During the course of my PhD, I cultivate my interests in trying to understand the fascinating distance between alloy composition, microstructure and mechanical behaviour. My thesis focused on the understanding of fatigue behaviour in RR1000, a nickel base superalloy employed as turbine disc in hot section of the turbine. To this aim, I have taken a multiple scale approach to investigate the deformation mechanisms; from dislocation behaviour at grain boundaries to mechanisms associated with deformed microstructure such as those encounters in shot peening processes or ahead of crack tip and finally short crack propagation and its relation to microstructure. I relied on various techniques from Trans- mission Electron Microscope (TEM) to X-ray computed tomography (x-ray CT) scans to investigate those different problematics.

Now, as a Post-Doctoral Research Associate, I am investigating multiple alloy systems to unveil the links between mechanical properties, microstructures and alloy compositions.
