Abstract
An investigation has been made of the deformation characteristics of metastableβ-phase in a commercial Ti-15 wt% Mo alloy within the temperature range −196 to + 146° C. Deformation occurred by slip, and by mechanical twinning on the {332} 〈113〉 system. Twinning occurred preferentially with decrease in deformation temperature. Enhanced ductility in tension, observed in the range − 94 to + 20° C, was attributed to the inhibition of “necking” resulting from strengthening by twin formation. A thinninginduced transformation occurred during foil preparation for electron microscopy.
