Research Interests:

Dr. Tan’s research interests focus on improving fundamental understanding of microstructure-property relationship of materials through experimental efforts and computational modeling in terms both of thermodynamics and kinetics, and developing advanced processing and combinatorial characterization techniques to enhance materials performance and improve analytical validity and efficiency. Dr. Tan’s research covers a wide range of materials, including metals and ceramics, for structural and functional applications.

Professional Experience and Education:

  • Research staff member of Oak Ridge National Laboratory (01/2010 – Present)
  • Visiting Scientist at Oak Ridge National Laboratory (05/2009 – 01/2010)

Research Experience:

  • 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)
  • Surface modification: Implemented plasma immersion ion implantation for NiTi shape memory alloys to improve their properties such as pseudoelasticity, hardness, wear and corrosion resistance, and biocompatibility (the Whitaker Foundation and AFOSR)
