Dr. Mingyue Sun is Professor and Deputy Director of the Material Processing and Modeling Division, Institute of Metal Research, Chinese Academy of Sciences (IMR, CAS). His research is focused on novel forming and microstructure-properties controlling technology for large forgings.
When pursuing PhD in the same institute, he contributed significantly to key technologies of forging, microstructure control and shrink fitting for a 20 meters long crankshaft. The work was rated as excellent, gained 11 patents, and created new output value over 3 billion RMB in five major companies. The research won the Liaoning Science and Technology Silver Award.
He also led a comprehensive study on microstructure control of SA508-3 steel for shape forming process, the results of which have been applied in forging companies and successfully produced several key components with ~5m in diameter of the AP1000 nuclear power plants. This project garnered 8 patents and was awarded Silver State Science and Technology Prize.
He sits on the Academic Committee of Chinese Plastic Engineering Society and Youth Committee of Chinese Materials Research Society. He holds over 40 patents and published over 30 peer-reviewed papers, including 50 technical reports for companies.
Recently, he promoted a novel metal processing method coined as "Bulk Metal Building". This technology can obtain homogeneous large steel products without preparing a heavy ingot, which effectively avoid serious solidification defects in large section steel. This novel method has been applied in the support ring with 15m in diameter for the 4th generation nuclear power plant, and main journal with 7.5m in length for water turbine. It is recognized as a disruptive technology and offered outstanding contributions to heavy forgings.
