Like most materials, the response of aluminium alloys to shock loading is strongly influenced by a number of factors such as chemistry, microstructure and processing. In this work, we examine the response of the aluminium alloys, 6061 and 5083, in particular, the evolution of lateral stress and shear strength behind the shock front. In 6061, the alloy is investigated in the solution treated (T0) and fully aged conditions (T6). Stress rise times and equilibration behind the shock front are observed to be quicker in T0 than T6, and has been attributed to fine Mg2Si particles inhibiting dislocation generation and motion in T6. In 5083, strength has also been observed to be relatively stable behind the shock front. In this case, the alloy was received in the H32 state, with the material previously worked by ca. 20%. Full one-dimensional recovery experiments have also been performed, confirming the above observations.
