СРАВНИТЕЛЬНЫЕ ЭКСПЕРИМЕНТЫ ПО ИОННОЙ БОМБАРДИРОВКЕ И МЕХНИЧЕСКОМУ УДАРНОМУ НАГРУЖЕНИЮ СПЛАВОВ СИСТЕМЫ AL-CU-MG

We have performed comparative experiments in order to confirm the hypothesis on the shock-wave nature of long-range effects under the particle irradiation of condensed matter, presumably coased by the emission and propagation of post-cascade shock waves in material. The experiments have included ion-beam exposure and mechanical shock loading of the VD1 and D16 alloys of the Al-Cu-Mg system. Found that changes in the microstructure of these alloys due to mechanical shock loading are similar to those initiated by ion bombardment (Ar +, 20-40 keV) at relatively low fluences (10 15-10 16 cm -2) gathered for 1-8 s. This is important evidence in favor of the important role of dynamic long-range effects, which were not considered in fundamental radiation solid-state physics until recently.
