Abstract： 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.
