Sagar Bhatt

Sagar Bhatt is a mechanical engineer in the Thermal and Structural Materials group within the Applied Materials Division at Argonne National Laboratory. His work focuses on predictive, physics-based modeling of material behavior in harsh environments, with an emphasis on materials produced by advanced manufacturing processes. Prior to his current role, he was a Postdoctoral Appointee in the same group, where he studied creep deformation in diffusion-bonded and additively manufactured microstructures.

Sagar’s current work centers on understanding how a material’s microstructure, including its grain morphology, defects, and features introduced during processing, shapes its mechanical properties and performance. More broadly, he is interested in using physics-based models to study and improve the performance of materials operating in harsh environments.

Sagar earned his Ph.D. in Mechanical Engineering from Rensselaer Polytechnic Institute in 2022, where his dissertation examined microstructure evolution in Ti-6Al-4V during thermomechanical processing. He also holds an M.S. in Mechanical Engineering from the University at Buffalo, State University of New York, and a B.Tech in Mechanical Engineering from Vellore Institute of Technology.
