Abstract
Synthetic SrSO4 single crystals have been indented and the rosettes revealed by etching around the indentations have been studied. The three-dimensional structure of the dislocation half loops formed by indentation has been revealed by the process of repeated polishing and etching of the same surface. From measurements of the displacements of the rosette arms and the corresponding depths, the inclination of the planes in which the dislocation half loops lie with the observation plane has been calculated; from this the slip planes are computed. The active slip planes thus computed are found to be {201}. dagger This is further confirmed by studying the rosette structure produced on a (201) cleavage plane by indenting that plane itself.Keywords
