Team R&D direction
The team takes the electromagnetic control technology of metal solidification process as the main line of research, and takes the in-situ visualization technology based on synchrotron radiation as the characteristic research means, covering the continuous casting process of non-ferrous alloy plates, strips, tubes and billets under the action of physical fields (electromagnetic field, ultrasonic field, pulsed electric field, etc.), the formation mechanism and preparation of composite/clad materials (metal to metal, metal to ceramic, etc.) interfaces, metal purification and purification In situ visualization of metal solidification process, interface theory and fine-grained technology of heterogeneous nucleation in alloy solidification, high entropy alloy design theory and bulk preparation technology, shape control technology of intermetallic compounds, doping design and solidification synthesis of thermoelectric materials, etc.
Team research achievements and application fields
The team leader combines solidification electromagnetic control with basic research of synchrotron radiation. Relying on the National Science Facility Shanghai Light Source and Beijing Light Source, he is the first person in academia to apply synchrotron radiation in situ visualization technology to research the dynamic mechanism of metal solidification electromagnetic field control. The team won one second prize of the National Technological Invention Award, two first prizes of provincial and ministerial science and technology awards, two second prizes, one Chinese Patent Excellence Award, and one gold medal of the Geneva International Invention Exhibition. The team has undertaken 1 national key research and development program, 2 national key research and development programs, more than 10 national key research and development programs, 1 major instrument development program of the National Natural Science Foundation of China, 1 National Natural Science Foundation for Distinguished Young Scholars Fund, 2 National Natural Science Foundation for Distinguished Young Scholars, and more than 20 general programs of the National Natural Science Foundation of China.

(3) Application achievements
Characteristic technology 1: In situ visualization method and device for alloy solidification (ZL201110438895.3)
Aiming at the problem of "black box" in casting solidification, a new method of in-situ visualization of synchrotron radiation X-ray under electromagnetic control was proposed, which realized in-situ observation and real-time imaging of alloy solidification behavior under electromagnetic control.
Solidification device
Characteristic technology 2: Non vacuum CuCrZr alloy round billet horizontal electromagnetic continuous casting technology (ZL201110286393.3)
The first horizontal electromagnetic continuous casting production line of CuCrZr alloy in the world has been established by electromagnetic induction "explosive" nucleation and controlling solidification structure and cracks. The defect free round billet with a diameter of 87mm, a length of 50m and a weight of 2.6t has been continuously cast under non vacuum.
