Conditions of Excitation of a Spinodal Decay of Unstable Liquid Phase in the Process of Metals Pulse Heating

The equations for spinodal and quasispinodal of a liquid phase are obtained; the area of existence of an unstable liquid phase on the phase diagram is certain. The established process of homogeneous nucleation of a vapor nuclei in overheated liquids in a spinodal area is considered, the formula for definition of characteristic time of development of this process is obtained. Velocity of heating of a liquid at which to pass through the spinodal in area of an unstable phase is possible is certain. Prominent features of spinodal disintegration of unstable liquid metal phases are considered.
