Dynamic properties evaluation of 2519A aluminum alloy processed by interrupted aging

Dynamic properties of 2519A aluminum alloy processed by interrupted aging are assessed in this work. At strain rate of 6900 s−1, the dynamic yield strength and absorption energy of this material are up to 690.9 MPa and 335.5 MJ/m3, respectively. Denser and finer θ′ precipitates contribute to these enhancements.
