Profile

Professor Gaurav Singh is a materials scientist specialising in the mechanical behaviour, processing, and degradation of advanced structural alloys across nuclear, aerospace, and energy systems.

Most recently, he served as a Postdoctoral Researcher at La Rochelle University (France), where his research investigated hydrogen diffusion and embrittlement mechanisms in nickel-based alloys. Before this, he was a Postdoctoral Research Associate at Rensselaer Polytechnic Institute (RPI, USA), evaluating the fatigue and fracture performance of advanced aluminum–cerium (Al–Ce) alloys for next-generation aerospace applications in collaboration with Ames National Laboratory and GE Aerospace.

Professor Singh earned his PhD in Materials Science and Engineering from the Indian Institute of Technology (IIT) Madras in collaboration with the Nuclear Fuel Complex (Department of Atomic Energy, India). His doctoral work focused on the thermomechanical processing, microstructural evolution, and mechanical response of zirconium alloys engineered for extreme nuclear environments. He earned his MTech in Metallurgical and Materials Engineering from IIT Roorkee, completing his master's thesis at RWTH Aachen University (Germany) on magnetron-sputtered high-entropy alloy coatings.

A recipient of the TMS Light Metals Award 2026, Professor Singh has published extensively in high-impact international journals and serves as an active peer reviewer for leading publications across materials science and engineering.

Research

During his PhD at the Indian Institute of Technology (IIT) Madras, Professor Singh investigated the thermomechanical processing, microstructural evolution, and mechanical behaviour of Zircaloy-4 alloys for nuclear applications in collaboration with the Nuclear Fuel Complex (Department of Atomic Energy, India). His research demonstrated the influence of processing parameters on microstructure, texture evolution, residual stresses, fracture behaviour, and mechanical properties using advanced characterisation techniques, including Scanning Electron Microscopy (SEM), Electron Backscattered Diffraction (EBSD), Transmission Electron Microscopy (TEM), and X-ray Diffraction (XRD).

Following his PhD, Professor Singh worked on additive manufacturing of AlSi10Mg, Al2024, 17-4 PH Stainless Steel, and Ti6Al4V alloys, focusing on their processing, microstructural characterisation, corrosion behaviour, and mechanical performance. During his postdoctoral research at Rensselaer Polytechnic Institute (USA), in collaboration with Ames National Laboratory and GE Aerospace, he investigated fatigue, fracture, and high-temperature stability of advanced Al-Ce alloys for aerospace applications. He is currently conducting research at La Rochelle University (France) on hydrogen diffusion and embrittlement in nickel-based alloys, with emphasis on hydrogen permeation, trapping mechanisms, and the influence of microstructure on structural integrity.
