"Tweed" structure of Fe-doped YBa2Cu3O7-δ
T. Krekels,G. Van Tendeloo,D. Broddin,S. Amelinckx,L. E. Tanner,Mohammad Mehbod,Eric Vanlathem,Robert Deltour +7 more
TL;DR: In this paper, electron diffraction and microscopy were applied to study the domain structure of Y-Ba 2 Cu 3 O 7−δ single crystals, which revealed a finer "tweed" structure of overlapping lenticular domains oriented along [120] and [1 1 0].

Electron microscopy observations of pretransition effects in alloys
G. Van Tendeloo,D. Broddin,C. Leroux,Dominique Schryvers,L. E. Tanner,J. Van Landuyt,S. Amelinckx +6 more
TL;DR: A number of alloy systems show structural modifications upon approaching a phase transition as discussed by the authors, which can be an ordering (or disordering) effect or a deformation modulation, and high-resolution electron microscopy allows one to deduce significant information on the transformation process.

Premartensitic Microstructures as Seen in the High Resolution Electron Microscope: A Study of a Ni-al Alloy
TL;DR: In this article, the parent phase effectively "prepares itself" for the eventual transformation via related lattice displacements, where the process is believed driven by anomalous temperature-dependent phonon effects.
Structural Phase Transformations in Alloys: An Electron Microscopy Study
G. Van Tendeloo,D. Schryvers,L. E. Tanner,D. Broddin,C. Ricolleau,A. Loiseau +5 more
- 01 Jan 1992
TL;DR: In this article, the structural changes occurring at interfaces, particularly antiphase boundaries, close to the order disorder temperature, are described, and the pre-transition modulations associated with the displacive austenite-martensite transformation.
Structural Instabilities Associated with Phase Transitions an electron microscopy study
G. Van Tendeloo,D. Schryvers,L. E. Tanner +2 more
- 01 Jan 1992
TL;DR: In this paper, electron microscopy combined with electron diffraction are highly qualified to provide microstructural data on phenomena occurring in the vicinity of phase transitions, such as pretransition effects occur for diffusion controled as well as for diffusionless transformations.
