Dr Dongdong Qu

Dr Dongdong Qu joined the Steel Research Hub in the May of 2015 as a postdoctoral research fellow after he achieved my PhD degree in Harbin Institute of Technology, China, where he studied the in-situ atomic level structural evolution of amorphous alloys under external loading and heating conditions.

He is currently focusing on the physical metallurgy of the ZnAl alloys coating onto steel substrate involved in the hot dip coating process. Fundamental topics of liquid ZnAl alloys structure, the reaction of liquid ZnAl alloy with steel substrate and ZnAl alloy solidification during the coating overlay formation are studied in the current Steel Research Hub project.

He has over five years of research experience in the atomic structure of amorphous alloys and the structure of liquid metals. His research background and understanding of the nature and development of liquid metal structure is an important skill set to understanding the development of metal coating microstructures. Advanced materials characterization technique adopted in this project include:

- Lab X-ray Diffraction
- Thin film coating layer texture
- Pole figure measurements
- Scanning Electron Microscopy (SEM) with energy dispersive spectrum (EDS)
- Transmission Electron Microscopy (TEM)
- Surface layer analysis techniques; X-ray Photoelectron Spectroscopy (XPS)

We expect to reveal the mechanism that is responsible for the ZnAl coating alloy reaction with steel and the solidification behaviour of the ZnAl overlay, and develop guidelines to control the coating process based on the metallurgical understanding of the ZnAl alloy coating formation.
