Abstract

Studies of the mechanical properties of the materials affected by 25-200 keV H+, He+, Ne+ and Ar+ ion irradiation in the range of fluences up to 2 1017 cm-2 based on the analysis of acoustic emission signals, kinetics of the surface deformations measured by laser interferometric technique and the variations of the surface acoustic waves propagation velocity are conducted. The acoustic emissions source mechanisms under various ion irradiation conditions are discussed and relative contribution various possible mechanism are indicated. The correlation of experimental results obtained by different methods of analysis is done.
