Aihan Feng is an associate Professor of Materials Scicene in Tongji University, China. She received the B.Sc., M.Sc., and Ph.D. degrees from the Harbin Institute of Technology, Harbin, China, in 1997, 2001 and 2005, respectively. She then worked as a Postdoctoral Fellow at the Institute of Metal Research, Chinese Academy of Science, Shenyang, China. In May 2008, she worked as a postdoctoral Fellow in the Department of Mechanical and Industrial Engineering, Ryerson University, Toronto, ON, Canada. Her current research intersts were as follows:
 Isothermal forging of magnesium, titanium alloy, Ti2AlNb-based alloy and titanium aluminide intermetallic alloys;
