Description

The formation of δ hydride in Zircaloy-4 has been studied using electron backscatter diffraction. Both intra-granular and inter-granular hydrides were observed. The intra-granular hydrides platelets prefer to interlink each other and form a chain-like configuration. Based on thermodynamic model, the formation mechanisms of the interlinked structure were analyzed. We found that the misorientation of two adjacent grains and the tensile stress near the tips of hydride platelets are the key factors affecting the appearance of the interlinked structure. (author)
