| Abstract: | The feature of recovery process in the plastically deformed Ni (contained 0.01%impurity) and the effect "of impurities on the recovery of defects were investigated by positron annihilation lifetime technique. The dislocation density in the sample of plastically deformed 10% and the effective concentration of the vacancies for the formation of vacancy clusters in such deformed sample were calculated. |

| Keywords: | positron annihilation nickel recovery vacancy dislocation vacancy cluster |
