Already in 1968 one of the present authors determined the activation energy for the rolling-texture transition in Cu-5%Zn as a spin off of an investigation of the strain-rate dependence of the rolling texture. In the present work this determination of theactivation energy is explained and discussed (whereas very few details were given in the original work), and an error in the original work is corrected. The activation energy for the texture transition is compared with recent values for the activationenergy for cross slip derived from atomic-scale modelling. After adjustment to a stress level corresponding to the stress in Cu-5%Zn during heavy rolling the theoretical activation energy for cross slip is pretty close to the activation energy for thetexture transition. It is concluded that the texture transition is governed by cross slip, and the detailed mechanism is discussed.
