Abstract

It has been found that autowaves can emerge at a phase transition of the first order, and their propagation is accompanied by self-oscillations of the temperature and phase composition of the medium. Conditions under which the mentioned waves can appear have been formulated. It has been shown that the propagation of autowaves leads to significant fluctuations of macroscopic parameters in a vicinity of the phase transition temperature.
