Background and activities

Background:

Yanjun Li (Born 1970),  professor of Physical Meallurgy.  He obtained his Ph.D in Materials Science and Engineering (1997). He had worked as Research Metallurgist at Hydro Aluminium (2005-2007), and Senior Research Scientist at Group of Materials Physics, SINTEF M&K (2008-2013) before he joined NTNU as a full professor in 2013.

Research Fields:

  • Solidification and casting ;
  • Homogenization, Precipitation strengthening, and phase transformation;
  • SPD and bulk nc/UFG materials;
  • Grain boundary engineering;
  • Materials simualtion by first principles calculation
  • Microstructure simulation models
  • Advanced materials characterization ( SEM, (S)TEM, APT, EBSD and XRD)
