Abstract
Atomic structures of hexagonal α’ martensites in Ti-6mass%Al-4mass%V alloys have been studied by means of aberration corrected high-resolution transmission electron microscopy and electron diffraction. There observed differences in atomic structures of the {1110}-type twin boundaries of the α’ martensites: stacking faults, a few atomic layers in width, was observed at the twin boundary for the as-quenched alloy after solution treatment at 1100℃ (above the β transus), while the alloy solution treated at 950℃ (below the β transus) showed a clear-cut twin boundary. The excellent ductility is observed in the latter alloy.
