实验表征为了更直观的表现出不同工艺路线下试样在不同状态下硬度的变化趋势,将最终结果绘制为如下所示的柱状图,结果如图4所示。
Experimental characterization in order to more intuitively show the change trend of hardness of samples in different states under different process routes, the final results are plotted as the following histogram, and the results are shown in Figure 4.
