N2 - The influence of combined addition of phosphorus and titanium on the microstructure of model Fe-Cr-Ni austenitic alloys irradiated at 700-873 K to 60 dpa has been investigated in comparison with that of a complex austenitic alloy (JPCA-2). At all temperatures, void swelling of the model alloys was suppressed with increasing phosphorus content or co-addition of phosphorus and titanium. The microstructures observed and calculation of defect processes showed that the suppressed void swelling was due to an interaction of phosphorus in solution with defects at lower temperature and needle-like phosphide acting as defect sinks at higher temperature.
