DISLOCATION GLIDE ON NONCOMPACT CRYSTAL PLANES IN COPPER

A single-shear creep technique was applied to copper single crystals i n order to generate a dislocation glide process on non-compact crystal planes (100), (110) and (131). Optical metallography and interference microscopy of slip lines on the surface have shown that the shear str ain was realized mostly by slip on the usual {111} planes and a massiv e non-compact glide probably did not appear. However, examples of non- compact glide from strongly stressed regions in the specimen are given . (C) 1997 Elsevier Science S.A.
