Research Staff and Team Lead, Nuclear Structural Alloys
Dr. Lizhen Tan joined the Materials Science & Technology Division in 2010. His research interests focus on advanced materials development and assessment for fission and fusion reactors. With over 10 years of experience in processing-microstructure-property relationship of advanced alloys, he has led and participated in multiple projects on assessing microstructural evolution, radiation resistance, mechanical properties, weldability, and corrosion resistance of a variety of advanced alloys. Recently, he has been leading the development of advanced ferritic-martensitic steels and ferritic alloys for use in the sodium-cooled fast reactor, light water reactor, and fusion reactor. He has more than 100 publications in peer-viewed journals, conference proceedings, book chapters, and technical reports.

- Alloy development: Enhanced the performance of ferritic-martensitic alloys by optimizing compositions and thermomechanical treatments (DOE).
- Aggressive environmental corrosion: Assessed the corrosion resistance of advanced steels, Ni-base alloys, SiC, and aluminum alloys exposed to supercritical water, liquid lead-bismuth, supercritical CO2, high-temperature air, and acidic environments, and improved the corrosion resistance as well as mechanical properties of representative alloys by means of grain boundary engineering, surface engineering, and severe plastic deformation (DOE, NACE, and ONR).
- Transport/reaction mechanism of fission products: Performed experimental studies on the transport/reaction of Ag, Cs, and Pd in/with ceramics (e.g., SiC, TiC, TiN, ZrC, and ZrN), which were studied in parallel by multi-scale modeling and simulation (DOE and NRC).
- Thermo- and radiation-induced segregation: Investigated segregation in advanced austenitic and ferritic-martensitic steels by in-situ fracture inside AES (DOE).
