Decomposition of the MANET steel under dual-beam irradiation

Abstract Decomposition of the MANET steel was observed by means of atom probing after 300 keV Fe + ion irradiation to 50 dpa and simultaneous implantation of 15 keV He + ions at a rate of 200 appm/dpa. At irradiation temperatures of 673 and 698 K weak periodical variation of the chromium concentration was observed. At irradiation temperatures of 723 and 773 K clusters with chromium concentration of up to 25 at% were detected.
