Numerical study of the phase transitions occurring in metals under the action of pulsed ion beams within the framework of the thermal spike model

Phase transitions occur in materials under the action of high-current high-power beams of charged particles. As a rule, such problems are solved within the framework of the heat-conduction equation. In this paper, studies of phase transitions are carried out within the framework of the thermal spike model, and both models are analyzed and compared. It is established that taking the electron gas into account significantly affects the dynamics of the crystal-lattice temperature and the dynamics of the phase transition.
