AbstractFracture toughness was found to decrease rapidly with increasing temperature in dispersionstrengthened GlidCop®Al-25 copper alloy both in the as-supplied condition and neutron irradiated to a dose of 0.3 dpa. Internal friction study revealed two-component peak. Grain-boundary sliding was recognized to be responsible for the low-temperature component of the peak, which disappears after irradiation and restores after the heating above 900 K. This points out that the changes in the particle — grain boundary interaction, apparently, due to the defects at the interfaces produced by irradiation are responsible for the drop of fracture toughness in A125 alloy.
