Srinivas Aditya Mantri

Dr. Srinivas Aditya Mantri is a Materials Scientist in the Nuclear Science and Engineering Division at Argonne National Laboratory. His research focuses on physical metallurgy, phase transformations, and the mechanical behavior of both conventionally processed and additively manufactured materials, with applications spanning aerospace, biomaterials, energy systems, and magnetic materials. Dr. Mantri earned his M.S. in Materials Science from the University of Cincinnati and his Ph.D. in Materials Science from the University of North Texas. His expertise includes additive manufacturing, advanced electron microscopy, deformation and failure mechanisms, and computational alloy design using CALPHAD-based approaches. His current research is centered on the development and additive manufacturing of advanced structural steels for nuclear energy applications, with an emphasis on linking processing, microstructure, and performance. In addition, he serves as the manager of the Metal Additive Manufacturing Laboratory (MAML) at Argonne.
