Abstract

Planar, high-index interphase boundaries developed during the α→γm transformation in a Ti-46.54% Al alloy were re-examined with a 3-D near-coincidence site analysis. Pairs of low-index planes, fulfilling the Zhang and Purdy [Philos. Magn. A 68 (1993) 279] minimum mismatch criterion, meet along their edges. Atoms at these edges commingle almost linearly, thereby producing a kinetic barrier to boundary migration.
