Quantitative measurement of displacement and strain fields in the ZrO2 layer during the transition to nodular oxidation
Source abstract
Abstract
Abstract We have performed a microstructural characterization of the oxide layer formed on a Zr-based alloy during high-temperature oxidation, focusing in particular on the nodular oxide. A number of dislocations were observed at the nodular oxide layers, and there were many more dislocations in the nodular oxides than in normal oxides. Normal and nodular oxides were analyzed using high-resolution transmission electron microscopy, and their strain fields were mapped using a geometric phase analysis. Our results confirm that the stress built up in the oxide layer has a huge impact on the occurrence of nodular oxidation and the formation of dislocations.
