Abstract

Abstract: Boron addition to a new polycrystalline nickel-based superalloy promotes the formation of a hitherto unreported aluminoborate phase, in the scale produced by oxidation in air at 900 °C for ~ 10, 000 h. Atom probe tomography provides unambiguous confirmation of this. The ramifications of its formation are discussed. Graphical abstract:
