【 摘 要 】

We have subjected the aluminium alloy 7010-T7651 to shock loading. A heterodyne velocimeter system was used to interrogate both the HEL and dynamic tensile failure (spall). It was shown that the HEL in the short transverse direction is higher than in the longitudinal direction whereas the spall strength is higher in the longitudinal direction. The increased HEL in the short-transverse direction is thought to be due to the increased number of grain boundaries due to the highly elongated nature of the grains along the rolling direction. The spall strength was measured and compared with other high-strength aluminium alloys and was found to be 1.61 GPa ± 0.19 GPa in the longitudinal direction and 1.20 GPa ± 0.01 GPa in the short-transverse direction.
