An experimental study of the double slip deformation hypothesis for face-centred cubic single crystals

Abstract

Abstract Direct x-ray measurements during deformation are compared with single slip and double slip calculations for rotations beyond the symmetry line. Both a literature survey of 152 face-centred cubic tests since 1923 and the present studv of 16 aluminium tests reveal that the use of the automatic double slip calculation for resolved data is not a reliable procedure. No test since 1929, including the present series, for which rotations have been measured during deformation have turned at the symmetry line in the manner predicted for the double slip hypothesis.
