- •
The cast 6063 alloy under solution treated (ST) and artificial aged (AA) were impacted at strain rates in the range of 1 × 10−3 to 3.5 × 103 s−1.
- •
The AA alloy exhibits an obvious positive strain rate sensitivity under dynamic compression. For the ST alloy, slight strain rate sensitivity is detected.
- •
The microstructure evolution during impact deformation resulted in different flow behaviors has been discussed in detail.
- •
The modified constitutive equation seems to be consistent with the experimental results.
