Abstract
The main features of dislocations in Cu-Zn-Al β phase exhibiting thermoelastic martensitic transformation have been analysed by means of electron microscopy and computer electron micrograph techniques. Two types of samples were studied : samples which were thermally cycled in the bulk state around the transformation range and two way memory samples which were obtained by temperature cycling with an applied stress. In both cases, most of dislocation line directions were near or coincident with directions of the β phase. In thermally cycled samples, type directions were also observed and in all cases dislocations has type Burgers vectors. In the thermally cycled under stress observed dislocations are in fact often dislocation dipoles in {110} planes and they are close to screw orientation.
