Compositional and isotopic profiles of a DU-10Mo grain boundary. (a–i) 3D element distribution maps for major alloying and impurity elements; (j) corresponding quantitative analysis of composition across the grain boundary (concentration in at% versus distance) via a 1D concentration profile; (k) 235U enrichment across the grain boundary. Error plotted in (j,k) is calculated based on point-counting error. The black arrow in (a) points towards the grain boundary analyzed.
