Abstract
It is proposed that the FCC-HCP martensitic phase transformation may be studied ultrasonically by measuring the effect of "optical" vibrations of extended dislocations on the [111] shear sound velocity and attenuation. A simple model for the behavior of such dislocations predicts a dip in velocity and a rise in attenuation as the transformation is approached.
