摘要：

A mechanically alloyed IN9052 aluminum alloy with an ultra-fine grained structure is characterized at three temperatures of 773, 848 and 863 K and over a strain rate range from 1 X 10(-3) to 100 s-1. The maximum elongation of 330% was obtained at an extremely high strain rate of 10 s-1 at 863 K. In the high strain rate range, where superplasticity was found, a relatively high strain rate sensitivity of more than 0.3 (n = 3) was obtained.
