“…Initial orientations are more easily rotated to the C and S orientations than to the B orientations at lower rolling temperatures, while the B component is found to be the strongest component in the center of the 3003 layer at higher rolling temperatures. This is in accordance with experimental observations from references [50][51][52]. The increase in the B component can be attributed to the increase of the strain-rate sensitivity index [50], to the additional activation of other, non-octahedral slip systems at very high deformation temperatures [51], and differential dynamic grain growth [52].…”

The recrystallisation behaviour and its effect on the crystallographic texture during solution heat treatment of thick aluminium alloy 7010 plates has been studied both on commercially hot rolled plates and on laboratory specimens deformed in plane strain compression. In addition to X-ray macrotexture analysis, individual grain orientation measurements within the recovered subgrains and the recrystallised new grains were performed by means of electron backscattering diffraction. Significant recrystallisation takes place during the solution treatment with almost no change in the macrotexture. This behaviour is explained by the balancing effect of randomisation of the texture during recrystallisation and texture sharpening within the recovered matrix regions.MST/3433

The main aim of this work was to develop a model with predictive capability for micro structural evolution during recrystallization and to identify factors that exert the greatest effect on the development of texture. To achieve this aim, geometric and crystallographic observations from two orthogonal sections through a polycrystal were used as input to the computer simulations, to create a statistically representative three dimensional model. Assignment of orientations to the grains was performed so as to optimize agreement between the orientation (ODF) and misorientation (MDF) distributions of assigned and the observed orientations. The microstructures thus created were allowed to evolve using a Monte-Carlo simulation. As a demonstration of the model the effects of anisotropy, both in energy and in mobility, stored energy and oriented nucleation on overall texture development were studied. The results were analyzed with reference to the various established competing theories of oriented nucleation (ON) and oriented growth (OG). The results suggested that all of oriented nucleation, mobility anisotropy, stored energy and energy anisotropy (listed in order of their relative importance) influence texture development. It was also determined that comparison of simulated and measured textures throughout the recrystallization process is a more severe test of a model than the typical comparison of textures only at the end of the process.
