The effects of neutron irradiation on the rate of contact melting were studied for a large number of pairs of metallic crystals, while the effects on the rate of dissolution were studied for NaCl crystals in water. In both cases, the rate was greatly increased immediately after irradiation, but it decreased with time to a constant value less than that of unirradiated crystals. Similar results were obtained for the dislocation density in irradiated KCl crystals. It is concluded that the observed contact melting and dissolution phenomena are due to an intense movement of the radioinduced defects in the relaxation process following irradiation, resulting in partial annihilation and a reduction in the dislocation density.
