Paper Abstract

The results of X-ray diffraction analysis of three Zr-based alloys are presented in this contribution. The tubular samples of ZrlNb, Zry4 W and ZIRLO alloys were simultaneously oxidized for various exposures in both pressurized VVER 1000 imitating water and water with 70 ppm Li as LiOH at 360°C. The effect of Li-environment was observed for all the characteristics obtained by means of XRD, i.e. residual stresses σ, krystallite size D and microstrains ε of oxide layers. The change of all the characteristics correspond to changes of corrosion kinetics in Li-environment for two types of the alloys: Zry4 W and ZIRLO. The behavior of ZrlNb alloy was found to be different. No effect of Li-environment was observed on stresses σ in metal underlying of alloys investigated.
