ABSTRACT
This article presents test results of influence of pre-oxidation of the Zircaloy-2 alloy at different temperature on hydrogen degradation. The specimens were oxidised in laboratory air at 350ºC and 700ºC. The samples were then divided into two groups. The samples from the first group ware tensed at 10-5 s-1 strain rate and simultaneously charged with hydrogen under constant direct voltage in 1 M sulfuric acid at room temperature. The samples from the second group were charged without any tension, then annealed at 400ºC for 4 h and finally tensed at the above strain rate. The SEM examinations were performed on the cross-sections and fracture faces of specimens.
