Speak: Prof. Tetsuya UCHIMOTO
Time: 13:50-14:40, Oct. 29
Magnetic properties are sensitive to various microstructure change of materials. Authors have been applied electromagnetic nondestructive testing methods such as eddy current testing (ECT), magnetic incremental permeability method (MIP), eddy current magnetic signature method (EC-MS) to evaluate various kinds of materials degradation. In this talk, several applications together with their measurement principles are introduced as follows:
1) Residual Strain Evaluation for Carbon Steels by EC-MS
2) Creep Degradation Evaluation for MIP
3) Hydrogen embrittlement Evaluation for Austenitic Stainless Steels by ECT.
Tetsuya Uchimoto received his B.Eng., M.Eng. and D.Eng. in Nuclear Engineering from the University of Tokyo, Japan in 1993, 1995 and 1998, respectively. He was a research associate at the Nuclear Engineering Research Laboratory of the University of Tokyo from 1999 to 2001. From 2001 to 2003, and from 2003 to 2017 he was Lecturer and Associate Professor, respectively, and since 2017 has been Professor, at the Institute of Fluid Science, Tohoku University. His research interests include evaluation of degradation of structural materials by electromagnetic nondestructive evaluation, such as austenitic stainless steels, Nickel based alloys and high Cr ferritic steels, structural health monitoring using eddy current testing and ultrasonic testing, and novel sensor development.Sist seminar 18213
