- 摘要:
- 为了得到扫描电镜中透射电子发生布拉格衍射形成的菊池线，采用自主绘制、加工的透射模式电子背散射
衍射技术的样品台，磨制含铜钢薄膜样品；通过调整待测样品与水平面的夹角、磷屏探头进入距离、待测样品与电镜极
靴距离等参数，分别检测与收集菊池花样。 结果表明：检测点越靠近含铜钢薄膜样品的冲击孔洞，样品越薄，则待测样品
与电镜极靴距离越小；磷屏探头离含铜钢薄膜越近，接收的透射电子信号越多，菊池花样越清晰 , 菊池花样与数据库晶
体结构信息匹配程度检测值越小。
In order to obtain the Kikuchi line formed by Bragg diffraction of transmission electron in scanning electron
microscope, the sample table of transmission mode electron backscattering diffraction technology was used to fabricate the
sample of copper containing steel film. The Kikuchi pattern was detected and collected by adjusting the angle between the
sample and the horizontal plane, the entry distance of the phosphor screen probe, and the distance between the sample and
the electron microscope pole boot. The results show that the closer the detection point is to the impact hole of the
copper-bearing steel film sample, the thinner the sample is, the smaller the distance between the sample to be measured and
the electron microscope pole shoe is. The closer the phosphate-screen probe is to the copper-bearing steel film, the more
transmitted electronic signals are received, the clearer the Kikuchi pattern, and the smaller the matching degree between the
Kikuchi pattern and crystal structure information in the database.
