Digvijay Singh, Ph.D. Ramanujan Faculty - Indian Institute of Technology, Roorkee
I am Dr. Digvijay Singh, a materials scientist specializing in the design, development, and characterization of high-performance alloys for extreme environments — including cryogenic temperatures, corrosion, hydrogen exposure, and cyclic loading. I currently serve as a Ramanujan Faculty Fellow in the Department of Metallurgical and Materials Engineering (MMED) at the Indian Institute of Technology (IIT) Roorkee, where my research focuses on developing next-generation cryogenic alloys for liquid hydrogen technologies, sustainable infrastructure, and advanced energy and aerospace applications. I am particularly interested in understanding the mechanisms of martensitic transformation in austenitic steels, such as austenitic stainless steels and medium/high-Mn alloys, with special attention to the influence of crystal orientation, phase stability, and stacking fault energy (SFE) on bidirectional transformation-induced plasticity (B-TRIP) phenomena. These studies aim to advance the development of next-generation fatigue-resistant steels for cryogenicapplications.
Prior to joining IIT Roorkee, I worked as a CNRS Researcher at the Institut Jean Lamour (IJL-CNRS), Nancy, and a Visiting Scientist at the European Synchrotron Radiation Facility (ESRF), France, where I developed a high-throughput in-situ thermo-mechanical (ITM) characterization platform utilizing high-energy synchrotron X-rays to study dynamic phase transformations in metallic materials under extreme conditions.
Before my tenure in Europe, I was a Postdoctoral Researcher at the National Institute for Materials Science (NIMS), Japan (2022–2024), where I investigated next-generation cryogenic steels for liquid hydrogen storage and seismic damping applications. My research at NIMS uncovered key insights into reversible martensitic transformations that enhance low-cycle fatigue resistance.
I earned my Ph.D. (2017–2021) from the Department of Metallurgical Engineering and Materials Science at IIT Indore, India, where I studied gradient nanostructuring (GNS) in metallic materials. This work demonstrated that GNS can significantly improve mechanical strength, corrosion resistance, and high-temperature oxidation behaviour, thereby contributing to the design of surface-engineered materials for structural applications.
