Abstract
The testing temperature impact in the range of ΔT=233-363 K upon tweed structure formation on aluminum single crystal foils with (100) [001] orientation under cyclic tension was studied. It was found that with increasing testing temperature the spacing (spatial period) of the tweed structure increases. The process activation energy which turned out to be close to one for the interstitial atom migration in aluminum Emi = 0.12±0.01 eV was determined by the dependence of the tweed structure spatial period versus the temperature. The results obtained are discussed in terms of synergetic effect being induced by: (i) nonequilibrium conditions of cyclic deformation, (ii) the easy glide of dislocation in transverse direction in Al, (iii) the various crystalline configurations, iv) the collective migration of interstitial atoms in the crystals.
