Dr Yun Wang
Senior Research Fellow

Summary

Dr Wang joined BCAST as a research fellow in December 2007. He obtained his PhD in materials science at University of Sheffield, and worked as a research fellow at University of Sheffield and University of Surrey.

Dr Wang’s main research interests are solidification processing, microstructural characterisation, heat treatment and phase transformation of light metals and alloys. His current research focuses on revelation of the nature of oxide films and other inclusions in alloy melt, understanding of heterogeneous nucleation mechanisms for Al- and Mg-based alloys, and microstructural characterisation of light alloys by high resolutuion electron microscopy, including aberration (Cs) corrected scanning transmission electron microscopy.
