Research Interests：

Advanced Metallic Materials for Marine, shipbuilding and Nuclear Engineering

Achievements:

The group of Metallic Materials for Marine and Nuclear Engineering currently has 7 teachers (1 professor, 2 associate professors and 4 lecturers), including 2 doctoral supervisors, 6 master's supervisors, 1 Heilongjiang Longjiang chair professor, 1 Heilongjiang Outstanding Youth Fund winner and 2 CNNC young talents. Guided by the demand for metallic materials in the fields of marine, shipbuilding and nuclear engineering, the group is engaged in basic and engineering application researches on designing, processing and manufacturing of novel and advanced metallic materials. This group broke through the key technology of purification of nuclear grade high-purity hafnium. The weldable nanoprecipitate-strengthened steels for ships has been developed. The group has won more than 30 projects, such as national key research and development projects and key projects funded by the National Natural Science Foundation of China, etc. The group has won several government and community awards. They have published more than 150 papers in academic journal, such as Sci. Adv., Adv. Sci., Acta Mater., Inter. J. Plast. More than 50 invention patents have been filed. Some of research have been applied to the industry. The group has maintained long-term cooperation with universities and research institutes in the field of marine and nuclear engineering in Russia, the United States, Ukraine and other countries.

We are recruiting young talents as Associate Professor, Assistant Professor and Postdoctoral researcher. International students are welcome to apply for PnD and master’s degrees in our group.
