Research Abstract |
This study aims at quantitative evaluation of micro-structural change by creep damage of high Cr ferritic steels by electromagnetic acoustic transducer (EMAT)-nonlinear eddy current testing (ECT) multi-sensor, and the followings were investigated. Examined were the relationship between structural change by creep damage and acoustic/electromagnetic properties. Finally, structure of EMAT-Nonlinear ECT multi-sensor was discussed to evaluate the micro-structural change by creep damage of high Cr ferritic steels.
