Abstract:

An investigation was made of the occurrence of ductile hydrides in Zircaloy-2. The results demonstrate that the tensile properties of hydrided Zircaloy are restored in the range 100-200C due to plasticity of the hydrides. The mechanism is not clear, but the temperature increase may change the generally accepted composition ZrH1.5 to a ductile form, or there may exist a complex relationship between the hydride phase and the zirconium matrix.
