Dr. Koichi Yagi worked as a researcher in National Institute for Materials Science (NIMS) (formerly National Research Institute for Metals (NRIM)), and he retired from NIMS in March 2006, and he is a private consultant for materials failure accident. He is working as a senior advisor of National Center for Materials Service Safety (NCMS), University of Science and Technology Beijing (USTB) from April 2009. His working area is safety and reliability of structural metals, life prediction of materials for plant maintenance, failure analysis and so on. When he worked in NIMS, he performed his part as a leader for the development of NIMS structural materials data sheet project including creep data sheet and the development of NIMS materials database. His main research areas were the study on creep-fatigue interaction of heat resistant steels, the study on creep crack growth behavior of heat resistant steels, the development of materials risk information platform and so on. He stayed in MPA Stuttgart as a visiting researcher from 1980 to 1981. He has organized many international conferences on creep, for example, 8th International Conference on Creep and Fracture of Engineering Materials and Structures, Japan (1999) and 4th Japan-China Bilateral Symposium on High Temperature Materials Strength (2001) (with Prof. Xishan Xie and Prof. Shantung Tu). He wrote and edited some books, for example, “Creep Properties of Heat Resistant Steels and Superalloys” which was written together with European and Japanese researchers and published from Springer in 2004. He played the active part for engineering societies, for example, as Japanese representative of JPVRC-EPERC-PVRC committee, Japanese representative of VAMAS (Versailes Project on Advanced Materials and Standards) steering committee and so on. He received JSME Medal for Distinguished Engineers from the Japan Society of Mechanical Engineers in 2007, Carl von Bach Medal from Stuttgart University in 2005, the Fourth Order of the Sacred Treasure from Japanese government in April 2016 and so on.
