Abstract
The results for mechanical testing and fractography of the ring samples, made of the experimental Zr–Nb–Sn–Fe alloy, are presented. The most reliable macro- and micro- parameters to quantify the fracture surfaces are defined. The correlations of some metrics for hydrides orientation with fracture parameters are investigated. The advantages and disadvantages of individual metrics are revealed. Threshold value for the near-surface radial hydride fracture at room temperature is obtained.
