摘要:
AbstractThe 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
