Abstract

Theoretical models are suggested which describe the transformations of low-angle tilt boundaries in high−Tc superconductors. Conditions are theoretically revealed at which the formation of split and amorphous dislocation configurations in low-angle tilt boundaries is energetically favorable. The results of the suggested models account for experimental data [M. F. Chisholm and D. A. Smith, Philos. Mag. A 59, 181 (1989)] on observation of low-angle tilt boundaries consisting of either split or amorphous dislocation configurations in high−Tc superconductors.
