AbstractPhase instabilities in a recently developed gum like alloy, Ti-24Nb-4Zr-8Sn (Ti2448), were investigated using conventional and aberration-corrected scanning/transmission electron microscopy. Athermal omega (hexagonal) and O' (orthorhombic) phases were found to be present in the alloy following solution treatment. A partial collapse of {111}(beta) atom planes was observed in the to phase, and a shuffle of every other {011}(beta) atom planes along < 0 (1) over bar1 >(beta) was observed in the O' phase particle. The presence of both the omega and O' phases in Ti2448 may influence the transition behavior under loading and may have significant impact on its mechanical properties. (C) 2018 Acta Materialia Inc.
