title = "Identification of a Ni0.5 (Al0.5-x Mnx) B2 phase at the heterophase interfaces of Cu-rich precipitates in an α-Fe matrix",
abstract = "A phase with the stoichiometry Ni0.5 (Al0.5-x Mnx) is observed at heterophase interfaces of Cu-rich precipitates in an α-Fe matrix, utilizing atom-probe tomography. First-principles calculations are utilized to determine the substitutional energies, yielding EMn→Ni =0.916 eV atom-1 and EMn→Al =-0.016 eV atom-1 indicating that the manganese atoms prefer substituting at Al sublattice sites instead of Ni sites. A synchrotron radiation experiment demonstrates that the identified phase possesses the B2 structure.",

Atom-probe tomographic analyses were performed at the Northwestern University Center for Atom-Probe Tomography (NUCAPT). The LEAP tomograph was purchased with funding from the National Science Foundation and the Office of Naval Research. Portions of this work were performed at the DuPont-Northwestern-Dow Collaborative Access Team (DND-CAT) located at Sector 5 of the Advanced Photon Source (APS). DND-CAT is supported by E.I. DuPont de Nemours & Co., The Dow Chemical Company, and the State of Illinois. Use of the APS was supported by the US Department of Energy, Office of Science, Office of Basic Energy Sciences under Contract No. DE-AC02-06CH11357. We extend our gratitude to M. E. Fine, D.
