Abstract
A study has been made of the geometry of common dislocation slip systems in solution-grown pyrene single crystals using surface etching and X-ray transmission topography. Good agreement is found between the results of the two examinations. The slip systems which readily contribute to plastic deformation are (001)[110] and [1text-decoration:overline10], (110)[1text-decoration:overline10], (1text-decoration:overline10)[110], (110)[001] and (1text-decoration:overline10)[001]. There is little agreement between the dislocation counts obtained from surface and bulk examination unless care is taken to avoid surface damage arising from etching and mechanical handling.Keywords
