Tensile tests were performed on the samples machined from as received AMg6 sheets to initial geometry, shown in Fig. 1(a). Two series of tests were performed to characterize the material in conditions of hot forming at the temperature of 415 ◦C: constant strain rate tests (Fig. 3) and stepped strain rate tests (Fig. 4). The stepped strain rate tests were performed with the strain rate changing in the range of 0.5 × 10−1–0.5 × 10−5 s−1 covering the strain
