【 摘 要 】

The effect of preliminary heat treatment on transformations of the grain structure of the aluminum alloy D16 under isothermal rolling at the temperature of liquid nitrogen and subsequent annealing was investigated. It was found that heterogenization by intensifying the nucleation of new grains facilitates the nanostructuring of the alloy during cryorolling, as well as the formation of a fine-grained structure upon static recrystallization at post-deformation annealing.
