Conclusions

  1. 1.

    In alloying of chrome-molybdenum steel with vanadium its radiation damage in the hardened condition is weakened in low-temperature (50–70°C) irradiation and strengthened with an irradiation temperature of about 300°C.

  2. 2.

    Restoration of the mechanical properties of steel irradiated in the hardened condition occurs during subsequent annealing at a higher temperature than in the same steel after hardening and high-temperature tempering, and with an increase in vanadium content the temperature of the start of restoration of the properties increases.

  3. 3.

    The experimental data obtained agree with the hypothesis of the influence of interstitial elements on the radiation damage of iron alloys and steel as a result of joining of vacancy-interstitial atom complexes or "molecular" type defects into vacancy-impurity accumulations.
