Abstract:
The influence of chromium on the radiation damage resistance of iron based alloys has been studied using conventional positron lifetime technique and a pulsed low energy positron beam. To simulate high neutron flux, the helium implantation has been used. Different levels of helium doses ( 6.24.10(17)-3.12.10(18) cm(-2)) corresponding to a local damage of up to 90 dpa were accumulated in a thin <1 mu m region. Four different binary FeCr alloys (2.6; 4.6; 8.4; 11.6 wt.
