A stress-corrosion-cracked Type 304 austenitic stainless steel was investigated by the Doppler broadening of annihilation radiation (DBAR) spectroscopy with a positron microbeam. Clear increase of S parameter was observed over 200-400 mu m areas from the stress corrosion cracking (SCC) crack. From the comparison of the DBAR spectra obtained from the stress-corrosion-cracked sample and plastically deformed sample, the increase of S parameter around the SCC crack was attributed to plastic-deformation-induced vacancies.
