根据ASTM E8，从热热轧(即轧制状态)板沿RD加工拉伸试样，在Instron-5569电子万能试验机上进行拉伸试验，室温应变速率为3.3 × 10⁻⁴s^-1。至少测试了三个样品以获得可靠的结果。

According to the ASTM E8, tensile specimens were machined from the hot-warm rolled (i.e., as-rolled) plates along RD. Tensile testing was performed using the Instron-5569 electronic universal testing machine with a strain rate of 3.3 × 10⁻⁴s^-1 at room temperature. At least three specimens were tested to obtain reliable results.
