Abstract

7003 Al alloy rolled plate possesses outstanding mechanical characteristics such as high specific strength and good formability, so it is used to manufacture some key structures of vehicle body. Therefore, figuring out the dynamic mechanical properties and response behavior are beneficial to further broaden its application. This paper mainly focuses on the mechanical response behavior, constitutive modeling and microstructural evolution of a 7003-T6 Al alloy rolled plate under various strain rates, through high-speed impact test, constitutive modeling, numerical simulation and microscopic characterization. The results show that the flow stress exhibits a positive SRS, while a negative SRS in the later stage of…
