Abstract

The effect of combined addition of phosphorus and titanium on dislocation loop formation and void swelling of austenitic Fe-Cr-Ni alloys under electron irradiation has been investigated with a HVEM. It was shown that phosphorus atoms (or phosphorus-titanium complexes) serve as nuclei for interstitial loops in the alloy containing both phosphorus and titanium as well as alloys containing phosphorus only. In the alloy containing phosphorus and titanium, vacancy loops were formed at higher temperatures compared with an alloy containing phosphorus only. As a result, a substantial suppression of void formation was observed, suggesting that the co-addition of phosphorus and titanium is very effective for increasing the swelling resistance.
