Summary

PERIODIC CRYSTALLIZATION AND MELTING PROCESSES OCCURRING IN THE COURSE OF RADIALLY SYMMETRIC OSCILLATIONS IN SUPERCOOLED LIQUIDS AND SUPERSATURATED SOLUTIONS ARE SHOWN TO RESULT IN HIGHER AMPLITUDES. THIS ENHANCES THE NONLINEAR INTERACTION OF SOUND WITH AN OSCILLATING NUCLEUS WHICH RESULTS IN THE PHENOMENON OF A SLOW PROCESS OF HEAT PUMPING INTO A NUCLEUS. THE LOCATION OF NUCLEATION SITES IN A STANDING SOUND WAVE DEPENDS ON THE DIMENSIONS OF NUCLEI AND THE SOUND FREQUENCY. PHASE TRANSFORMATIONS MAY MARKEDLY INCREASE THE ABSORPTION AND DISPERSION OF THE SPEED OF SOUND PROPAGATING IN CRYSTALLIZING LIQUIDS AND AN INCREASE IN THE AMPLITUDE OF THE OSCILLATIONS OF CRYSTALLIZATION NUCLEI ENHANCES THEIR INTERACTION WITH EACH OTHER.
