摘要：
Defects introduced at room temperature in YBa2Cu3O7 - δ ceramics during high stress plastic deformation tests were characterized by transmission electron microscopy (TEM). Dislocations with 〈100〉 Burgers vectors gliding in the (001) plane have been found to control plastic deformation. Glide dislocations interact strongly with mirror twin boundaries in the orthorhombic phase. Out-of-equilibrium shapes of dislocations evidenced in the tetragonal phase reveal memory effects of twin locations in the orthorhombic phase. © 1990.
