Nanoscale dynamic and long-range effects under cascade-forming irradiation

Mechanical properties and fatigue of extruded D16 alloy profiles of the Al-Cu-Mg system after ion irradiation

“…This phenomenon may be due to the fact that small elastic deformations occur under conditions of multi-cycle fatigue [6,7]. Moreover, the surface and the volume of the irradiated sample are subjected to instant (for several seconds) ion-beam radiation annealing [3]. As a result, both the surface and the volume become almost free of deformation defects.…”

“…It is widely used as a structural material in various fields of modern technology, including aircraft construction [1,2]. The changes in the microstructure, phase composition and mechanical properties of cold-worked VD1 and D16 alloy sheets (Al-Cu-Mg system) 2-3 mm thick after Ar + ion irradiation were previously presented in [3]. The ion-beam treatment regimes were selected to ensure the softening of these alloys to the required level of properties, which allows further cold-rolling of the alloys.…”

“…The ion-beam treatment regimes were selected to ensure the softening of these alloys to the required level of properties, which allows further cold-rolling of the alloys. Based on these results, we patented the technology of intermediate radiation annealing of commercial aluminum alloys during their cold rolling, which provides a 2-3 times reduction of labor and energy consumption of the processes as compared to heat treatment [3].…”

Structural-and-Phase Transformations in Fe-4.10 and 7.25 at.% Mn Alloys under Intensity External Actions

“…It is clear that if the medium is in a state of thermodynamic equilibrium, then external disturbances will reversibly or irreversibly deflect it from this state. Media that are in a certain intermediate, metastable state with increased energy, under intense external influences, can, on the contrary, undergo transformations with a transition to states closer to equilibrium [1][2][3].…”

“…There are a large number of examples of the formation of nonequilibrium highly defect states under the action of continuous and powerful pulsed ion beams [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. In works [1,3,[27][28][29][30][31][32], reverse processes of instantaneous rearrangement of nonequilibrium (metastable) media during ion bombardment at anomalously low temperatures with the transition of these media to states approaching equilibrium as much as possible were found. In papers [1,30,31], on the basis of experimental [27][28][29]32] and theoretical studies the idea has been put forward of using cascade radiation shaking under cascade-forming types of irradiation instead of temperature for a gigantic increase in the low-temperature atom mobility.…”
