This session was chaired by Prof. E. Akiyama (Tohoku U), Assistant Prof. J. Xu (Tohoku U). This session included 5 presentations and the topics were relatively concentrated. Most of the works focused on the role of hydrogen on the material degradation, including oxidation, tribocorrosion. Other works were related to the size effect on fatigue property and non destructive technique development.

The participants included Mr. Runsheng Gao, deputy director of the science and technology division, Ministry of Education, China; Ms. Jia Zhuang, director of Department of International Cooperation, Ministry of Science and Technology, China; Prof. Sadayoshi Ito, vice president of Tohoku U; Prof. Toshiya Ueki, vice president of Tohoku U; Prof. Tetsuo Shoji, academician of Academy of Engineering, Japan; Prof. Dongbai Sun, vice president of USTB, Prof. Ge Wang, vice president of USTB and other related researchers and staffs from both sides.

Close meeting on November 18, 2016

The closing meeting was held in the morning of November 18th, 2016 in the administrative building of USTB. The meeting mainly includes two parts: the first one is the summary of the workshop help on November 17th and the second one is the discussion about the road map of the joint laboratory. The meeting was chaired by Prof. Tetsuo Shoji.

Part 1: Summary of the workshop

Section 1 Materials Performance Evaluation in Energy Conversion System

This section was chaired by Prof. Y. H. Lu (USTB) and Associate Prof. Y. Takeda (Tohoku U). In this section the presenters showed common concerns about the protective oxides forming on materials and microstructure of the material by using surface analysis techniques such as SEM/TEM and electron spectroscopy. Some special experimentation triggered the interests of participants. Most of the concerns were related to the material performance under LWR, USC, A-USC environments.

Section 2 Surface Science and Corrosion

This section was chaired by Prof. Y. Jin (USTB) and Assistant Prof. H. Abe (Tohoku U). The contents of the presentations included FEM simulation of corrosion, corrosion measurements and microstructure characterization by synchrotron radiation, FAC modeling and experiments etc.

Session 3 Material-Performance Modeling, Simulation and Experimental

This section was chaired by Prof. L. B. Wang (USTB) and Prof. Y. Chen (Tohoku U). The topics were relatively scattered in this section, varying from first principle calculation to non-destructive technology, from strength/fatigue evaluation to surface/interface analysis. So it was suggested that some bridges can be built among different topics, such as developing computation tools and common methodologies etc.

Session 4 Hydrogen Induced Degradation and Fatigue

This session was chaired by Prof. X. C. Ren (USTB) and Prof. E. Akiyama (Tohoku U). Similar with Section 3, the topics in Section 4 were scattered too, ranging from corrosion/embrittlement to purification and alloy development. Some work concerned the role of hydrogen in metals. Especially, Prof. Komazaki et. al utilized a hydrogen as a sensor for degradation measurement such as fatigue and creep.

Part 2: Road map of the joint laboratory

Joint research proposal

Group leader of each group should work together and take a lead for promotion of possible matching of research area. Group leaders are to submit the report to the Directors hopefully within two month. Every group is expected to prepare to deliver a cooperation program proposal to funding agencies or industry. According to the current international cooperative program policies, three kinds of project are available.

• 1) Only by Ministry of Science and Technology, China (MOST) financial support;
• 2) Jointly support by Chinese government (Ministry of Education (MOE) and National Natural Science Foundation of China (NSFC)) and Japanese government (Japan Society for the Promotion of Science (JSPS));
• 3) NSFC can support the international cooperation.

According to the summary of the workshop, Surface, interface and oxides seem to be common concerns. Besides, Tohoku part will assign a person to contact USTB part for the proposal information and to distribute the requirements to Tohoku part.

Possible annual events and collaboration schemes

Based on the discussion, the following events were taken into consideration as the annual events and the next two-day workshop is to be help in Sendai in Nov. 2017.

• 1) Annual Workshop
• 2) Students Visit
• 3) Faculty Mutual Visits
• 4) Students/Young Scholar Summer School
• 5) Collaboration with other USTB/Tohoku U activities

Possible collaboration schemes would include the following items:

• 1) Integration of NDT evaluation;
• 2) Combined AE EMW during the fracture processes such as concrete etc.;
• 3) Multi-scale modeling and simulation;
• 4) Share the database;
• 5) Joint course for graduate students on MSM;
• 6) Friction modeling;
• 7) Share the facilities (Prepare the list of facilities at both side).

New Campus Visit on November 18, 2016

The New campus visit was held in the afternoon of November 18th, 2016 in Changping district. Most of the Tohoku U members participated in the visit under the guidance of USTB members. Three laboratories in the new campus were visited, namely high temperature high pressure laboratory, multi-phase flow laboratory and atmosphere corrosion laboratory. These three under-constructed laboratories represented the world leading level in their areas, giving the Tohoku U members a deep impression. The USTB members introduced the design and function of the facilities in the three laboratories and also discussed some technical issues with Tohoku U members.
