Investigation of Thermoelastic Effects in Metals in the Frame of the Modified Thermal Spike Model

Cover Page

Abstract


A numerical investigation of a thermoelastic waves arising in a nickel sample under the action of the uranium heavy ion high energy 700 MeV is made on the basis of a thermal spike model which is modified by adding to it move equations. It is shown that the arising maximal strength of the thermoelastic waves exceeds hundred times ultimate strength of a samples material on the axis of a track. The time dependence of the electron gas and ion lattice temperatures, of the thermoelastic waves strength are determined at a different distance from center of track. The time dynamic change is also determined of the maximal region within which thermoelastic strength exceeds ultimate strength of a samples material. By moving away from the center of a track along the radius, the amplitude of the thermoelastic waves will decrease inversely proportional to the radius.
