Crystal structure of high-Zr inclusions in an alloy containing U, Pu, Np, Am, Zr and rare-earth elements
Abstract
Researchers commonly observe high-Zr inclusions in actinide-Zr alloys. As there is very little published data on the crystal structures of these inclusions, it has generally been assumed that the inclusions were impurity-stabilized a-Zr. However, new electron-diffraction data from two high-Zr inclusions in an alloy containing U, Pu, Np, Am, Zr, and rare-earth elements show that these inclusions are not a-Zr (which has a hexagonal structure) but instead have a face-centered cubic structure. This data is unique in that it combines single-crystal diffraction patterns and microchemical analyses from individual inclusions. More data on other high-Zr inclusions is clearly required. However, the present results suggest that caution is needed in assuming that all high-Zr inclusions in actinide-Zr alloys are a-Zr.
