Understanding phase separation and segregation mechanisms.
Steels and high entropy alloys are very important engineering materials. Understanding the phase separation and seggregation mechanisms in these alloys is extremely complex. And controlling them is even more challenging. However, it is critical to evaluate and understand the thermodynamics of these alloys. In this project, we have designed several thermo-mechanical treatments and characterization routines to understand the influence of various material defects and their interactions with wide range of alloying elements used in these materials.
