Research Area

  In general, Dr. Chen’s main research interest is in physical metallurgy of steels with an emphasis on thermodynamics and kinetics. His PhD project was thermodynamics and kinetics of phase transformation in steels, while his research area was then extended to other topics which are linked to thermodynamics and kinetics. In the past 5 years, he has worked on the following topics: (i) Fundamentals of phase transformation in steels; (ii)Thermo-kinetic design of advanced steels for automotive applications and fusion energy applications; (iii) Hydrogen embrittlement with an emphasis on thermodynamics and kinetics of H diffusion and trapping in the multiscale microstructure; (iv) Additive manufacturing of advanced steels.
