Vibrations of coherent martensitic interphase boundaries

Harmonic flexural vibrations of a coherent interphase boundary under martensitic-type structural transformations are considered in terms of the elastic-continuum thermodynamics. In linear approximation, an integrodifferential equation of motion is obtained, and it represents the boundary as a non-local vibrating system with damping. The interphase-boundary dynamic susceptibility describing a response of the boundary to a small external disturbance is calculated. For a model finite interphase boundary, the vibration equation is solved numerically.
