    Abstract

    Two candidate materials for the blanket components of ITER were studied by the internal friction method. For low-activation martensitic F82H steel measurements of anelasticity were carried out in the temperature range of 80–500 K after preliminary electrolytical hydrogen charging. A broad multicomponent internal friction peak was detected in hydrogen-charged F82H steel in the temperature range of 100–450 K at a frequency of 1 Hz. The effect of the amount and the type of strengthening particles on the internal friction were clarified for CuAl25, CuAl60 and CuAl25 + TiC GlidCop™ dispersion strengthened copper alloys in the temperature range of 300–1000 K. The effect of neutron irradiation on internal friction of CuAl25 alloy is also discussed.
