Abstract
Defects in the form of twins, slips, kinks and cracks have been studied at room temperature by transmission electron microscopy. In highly aligned YBa2Cu307-x, multiple twinning can be observed, where the orientation of twin planes is varied by accommodation by slipping and kinking. Suitable (TIO) {1l0} slip systems are able to occur in this material. Formation of cracks on subgrain boundaries may occur after twinning in order to relieve transformational and thermal stresses.https://doi.org/10.1071/PH890419
