The equivalent true stress-logarithmic strain curves obtained from the compression tests at different temperatures and strain rates. Nine different deformation temperatures, namely 323, 373, 473, 573, 673, 773, 873, 973, and 1073 K, and three different strain rates, namely 0.01, 0.1, and 1.0 s-1, were used in compression tests. All tests were performed at isothermal loading conditions. The uniaxial compression tests were performed in a Bahr DIL 805A/D deformation dilatometer. Cylindrical specimens with a diameter of 3 mm and a height of 6 mm were extracted by wire electrical discharge machining from the as-delivered hot-rolled sheet along the rolling direction.
