摘要：

The structure and mechanical properties of nanocrystalline aluminum alloy 1570 obtained by means of severe plastic deformation have been studied. Being tested in a temperature range from 300 to 400 degrees C, the alloy exhibits high-strain-rate superplasticity. At 400 degrees C, the superplasticity is manifested in a very broad range of strain rates, extending from 5 x 10(-3) to 1 s(-1).
