用X射线衍射仪(xrd)对物相结构进行了表征,试样分别沿复合板轧向取样。采用机械研磨、抛光、4% nital溶液腐蚀的制备纵向横截面试样,使用X射线衍射仪进行物相分析。
The phase structure was characterized by X-ray diffractometer (xrd), and the samples were sampled along the rolling direction of the composite plate. The longitudinal cross-section specimens were prepared by mechanical grinding, polishing, and corrosion in 4% nital solution, and the phase analysis was performed using an X-ray diffractometer.
