Abstract

To investigate the irradiation properties of Mo-Re alloy of low Re content (atm%: 0%∼8.4%), Mo-Re alloy films were irradiated by 200 keV xenon ions at the dose of 5×1015 ions/cm2. Different irradiation effects were observed on the samples of different Re content. While the sample of pure Mo remained the same after irradiation, obvious localized amorphization phenomenon took place in the sample with Re content of 8.4%. So it is possible that Mo-Re alloy with low Re content might break down for the irradiation induced amorphization process. The formation mechanism of amorphous regions was then discussed by irradiation experiments at ion dose from 1×1015 to 5×1015 ions/cm2, by which the amorphization process developing from lattice damages to amorphous clusters, and finally to amorphous regions, was connected with the increase of irradiation dose step by step.
