Supplement, pp. S414-S419 . https://doi.org/10.1016/j.jnucmat.2013.03.028
In recent years, material development for ITER blanket components has been fervent; yet, a lack of materials data has been identified by the ITER International Organization (IO) and other ITER parties. Therefore, extensive work on assessment of mater

Hydrogen behaviour in martensitic F82H steel was studied by internal friction. A broad internal friction peak was found in the temperature range of 100–450 K. It was shown that the peak consists of one relaxation component and two components corres
