Knapp, J. A.; Follstaedt, D. M.

The lattice location of Sb trapped at TiC precipitates in Fe has been determined. Channeling analysis of ion-backscattering and ion-induced characteristic x-ray yields from Fe and Sb showed a substitutionality of greater than or equal to 50% for trapped Sb relative to the Fe lattice for ion beams incident along Fe (100), (110), and (111). In contrast, Ti x-ray yields showed channeling through the oriented TiC precipitates only along Fe (100). We conclude that Sb is trapped at interfacial Fe sites adjacent to TiC precipitates, rather than within the TiC.
