Depth resolved positron Doppler broadening spectroscopy was used to investigate the effect of neutron irradiation (simulated by self-implantation with Fe ions) on the defect structure of Fe-Cr alloys with different Cr content (2.5at% - 12at%). Different defect situations depending on the Cr content were found for the alloys.

Keywords: Fe-Cr alloys; Positron Annihilation Spectroscopy; ion implantation induced damage
