根据GB∕T 228.1-2010制备拉伸试样,保证样品整体光滑平整无裂纹,根据计算标定标距后,在美国Instron公司生产的Instron3369万能试验机上以1mm/min的速率进行拉伸试验,得到轧制样品的拉伸性能数据。
The tensile test specimens were prepared according to GB/T 228.1-2010 to ensure that the specimens were smooth and flat without cracks. After calibrating the calibration distance according to the calculation, the tensile test was carried out on the Instron 3369 universal testing machine produced by Instron in the United States at a rate of 1 mm/min. Tensile performance data of rolled samples.
