Drawing on their leadership in materials simulation and design, advanced microscopy and materials fabrication, University of Wisconsin–Madison engineers have developed a method for tuning the radiation resistance of high-entropy carbides. This new class of advanced ceramic materials has applications in fusion and next-generation fission reactors, as well as other high-temperature and extreme environments.

Sridharan and Kasturi Narasimha Sasidhar, an assistant scientist in Sridharan’s group, have demonstrated a new approach for restoring stainless steel’s corrosion resistance that could be much faster and potentially less expensive than conventional high-heat remediation methods.

NAMRG Director Kumar Sridharan, Grainger Professor of Nuclear Engineering & Engineering Physics and Materials Science & Engineering has been named Vilas Distinguished Achievement Professor in recognition for his contributions to research in materials for nuclear energy systems, materials science, metallurgy, and surface engineering of materials, and education.  Sridharan is also Fellow of American Society for …
