It was found that implantation, which causes radiation damage with 36 dpa, results in the formation of α'-martensite. At higher fluences of implanted ions, the amount of α'-martensite increased, reaching 86 at.% within the irradiated layer. Annealing in the temperature range of 600-850 °C resulted in the observed reverse transformation of α'-martensite to γ-austenite.
