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.本数据集包含不同温度及应变速率下压缩试验所得的等效真应力（true stress）-对数应变（logarithmic strain）曲线。试验共设置9种变形温度，分别为323、373、473、573、673、773、873、973及1073开尔文，同时采用3种应变速率，分别为0.01、0.1及1.0 s⁻¹。所有试验均在等温加载条件下进行。单轴压缩试验在Bahr DIL 805A/D型形变膨胀仪中完成。试验试样沿轧制方向从供货态热轧板材中通过线电火花加工（wire electrical discharge machining）切取，为直径3 mm、高度6 mm的圆柱状试件。
