Selective-etching methods have been developed for visualizing dislocations and other defects in C6(l single crystals. The nature of the changes which occur in the actual crystal structure as the result of plastic deformation during microindentation of the surface was studied. The crystallography is analyzed. Aspects of dislocation glide and crack formation in C6(l crystals are analyzed. Effects which result from holding the samples in air at various temperatures and in a solvent are described. Effects of illumination of the crystal with visible light are also described.
