|Abstract:||The alpha-bety phase transition of a zirconium alloy doped with 1 mol% of niobium (E110 alloy) is investigated using dierential scanning calorimetry. The onset and endpoints of the transition are identied from the measured heat ow signal and from the integration of the observed peak the extent of the alpha-beta phase change is calculated as a function of temperature. The experiment has been performed at dfferent heating rates and a shift of the onset temperature with increasing heat ing rate was observed. From the dataset the equilibrium transition curve has been extrapolated and compared with other types of zirconium-based cladding materials. Key words: fuel cladding, calorimetry, reactor safety, zircaloy|
