The microstructure in the Zr-Nb alloys have crucial impact on the material performance in-reactor. The microstructure is a function of material chemistry and the manufacturing process. This report provides an overview of Zr alloy manufacturing process and relationship between fabrication, microstructure and in-pile performance.
The report covers the impact of manufacturing on microstructure and in-reactor performance of Zr-Nb alloys. The report was co-authored by Russian scientists involved in the development of the Russian Alloys E110, E635 and E125.
