Effect of strain rate on impact response and dislocation substructure of 6061-T6 aluminum alloy

A study is conducted of the impact response of Al 6061 alloy deformed in the 10 exp 3 to 4 x 10 exp 3/sec strain rate range as well as of the dislocation densities and configurations thus generated. The relationship between dislocation, density, size, flow stress and strain rate is discussed in term...

Summary:A study is conducted of the impact response of Al 6061 alloy deformed in the 10 exp 3 to 4 x 10 exp 3/sec strain rate range as well as of the dislocation densities and configurations thus generated. The relationship between dislocation, density, size, flow stress and strain rate is discussed in terms of the dislocation structures observed. (AIAA)
