Micro-scale mechanism for cyclic deformation behavior in zirconium under low-cycle-fatigue loading
2024, International Journal of FatigueUncovering the hydride orientation-mediated hoop fatigue mechanism in a zirconium alloy cladding tube
2022, International Journal of PlasticityCitation Excerpt :Hydrogen-related degradation is highly dependent on strain range and hydride content (Isfandbod and Martínez-Pañeda, 2021). The fatigue life further decreases with increasing strain range and hydrogen content (Tan et al., 2006; Zhou et al., 2012). This is because hydrides often act as favorable paths for crack growth, thus increasing their growth rate (Suman et al., 2017; Sunil et al., 2016).

2022, Journal of Nuclear MaterialsDeformation mechanism and cyclic stress response of Zircaloy-4 alloy cladding tube during low cycle fatigue at room temperature
2022, International Journal of FatigueCitation Excerpt :It is well known that LCF failure of polycrystalline alloys is a complex physical process including plasticity strain accumulation, crack initiation and propagation [7]. Such cycling deformation and damage usually related to many factors involving grain size [8], texture [9–11], temperature [12], strain amplitude [13], strain rate [14], surface condition [15], presence of hydride [16–18] and inclusions [19], etc.. Among them, strain amplitude plays a critical role on stress response of Zr-4 alloy during LCF tests.
Microstructural and crystallographic analysis of hydride reorientation in a zirconium alloy cladding tube
2020, Journal of Nuclear MaterialsLow cycle fatigue properties of hydrogenated welding sheets of Zr–Sn–Nb alloy using funnel-shaped flat specimens
2020, Nuclear Engineering and TechnologyCitation Excerpt :Li et al. [5] used the funnel-shaped flat specimen to complete the low cycle fatigue tests of textured zircaloy-4 by controlling the radial strain amplitude at the root of the funnel. Tan et al. [6] and Cai et al. [7] applied the same method to investigate the effect of zirconium hydrides on the cyclic deformation behavior of Zr–Sn–Nb alloys. However, the detail that how to transfer radial strain amplitude to axial strain amplitude effectively had not been explained in these works.
