Description

In order to clarify the interaction between a vacancy and solute atoms in Fe alloys positron annihilation lifetime experiments were performed for the Fe-Cr alloys electron-irradiated at 77K. The isochronal annealing experiments showed the increase of the positron lifetime which corresponds to formation of microvoids. This temperature was about 200-220 K for pure Fe and it did not increase so much even for high-concentration Cr alloys. This suggests that the interaction between a vacancy and Cr atoms is not so strong because of small difference of the atomic size between Fe and Cr
