“…The enhanced effect of thermal cycling on the stress reorientation is, to a certain extent, similar to the phenomenon of hydrogen supercharging in zirconium-based material that can be achieved by repeated heating and cooling [31][32][33]. Supercharging was attributed to the incomplete dissolution of hydride precipitates.…”

“…In the first increasing stage both results follow the same behavior and similar values of the relative resistance change attributed to the H dilution in the a-Zr phase. Using this curve as a reference, the observed resistance change corresponds to %93 ppm in weight of dissolved H. By taking into account the resistance change per atomic fraction at 603 K, reported in the pioneering work of Mishima et al [11], a H concentration of 150 ppm can be estimated. In both cases this point is close to the limit of terminal (or maximum) solid solubility (TSS) %110 ppm for hydrogen for different Zr alloys measured at 633 K [12][13][14].…”
“…TSS of hydrogen in zirconium alloys is observed to increase with increase in temperature. At ambient temperature TSS of hydrogen in zirconium alloys is less than 1 g/g [44][45][46][47][48][49][50][51][52][53][54][55][56][57]. Hence, at ambient temperature almost all the hydrogen in zirconium alloy will be present as hydride.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
