The inevitability of a phase explosion of a liquid under pulsed heating conditions at a rate exceeding 108oK/sec follows from the thermodynamics and kinetics of liquid passage into vapor. The progress of this process in metallic fluids follows from tests with the electrical explosion of conductors. Meanwhile, as a rule, the possibility of a phase explosion is excluded in the description of the effect of powerful light radiation on a metal and the metal-rupture process is explained by evaporation of the substance from the surface of the target [52]. It is completely conceivable that such an approach may not yield an accurate description of this important physical process. This example convincingly proves the need for further and more detailed research on the phase explosion of fluids and the different aspects of its appearance.
