Non-destructive Techniques Study of the Fe-Cr Based Alloys

摘要

Non-destructive method, positron annihilation lifetime spectroscopy (PALS) was applied as an evaluation tool for microstructure study of the four different Fe-Cr alloys. This paper describes ion implantation technique as a tool for creating microstructure defect in structural materials, similar to radiation damage in nuclear facilities. In present state of the research non implanted specimens were measured using PALS, TEM and XRD. The results show the dependency of positron lifetime in defects on the Cr content. These results are necessary in further PALS spectra analysis of the implanted specimens.
