摘要：

A study was carried out to investigate the peculiarities of the change of grain size with the increase of sample elongation under superplastic deformation (SPD) at maximum strain rate sensitivity of an aluminium alloy with initial completely recrystallized ultra-fine grain structure. The mean grain size increased greatly with strain increases up to 100-150%, then, changed comparatively weakly or even passed the maximum at the mentioned strains. The development of dynamic recrystallization at SPD of the studied alloy was established in the region of strains corresponding to the maximum of index.
