This invention provided a method for acquiring nano-precipitate images based on scanning electron microscope backscattering mode. The following steps included in this method: sample pre-treatment, electron double spray thinning, low-temperature corrosion, scanning electron microscope capture images, and the morphology of nano-precipitates image captured. To get higher imaging quality of the nano-precipitate image of steels obtained from scanning electron microscope, this invention reduced the thickness of the sample to obtain the purpose of improving the conductive and reducing the magnetic. Compared with the traditional sample preparation and characterization, higher magnification and clearer images can be obtained to observe the precipitate morphology, size and distribution statistics.
