Abstract
A kinetic model of nonequilibrium melting of a metal under conditions of critical heating by a nanosecond volumetric heat source is formulated. The proposed approach takes into account the characteristic features of the process: strong nonequilibrium of the system and thermodynamic fluctuations of the order parameter, which play a significant role in the vicinity of the critical phase transformation point, especially when the point of absolute instability of the system is reached. The curves of dependence of the model thermodynamic potential on the order parameter for various values of the superheat of a copper sample are calculated. During critical overheating, the minimum corresponding to the solid state disappears, turning into an inflection point. The solid state becomes completely unstable.
