Background

With the continuous promotion of the research level at present, the traditional two-dimensional metallographic structure observation can not meet the requirements of high-end experimental science. Not only when the microstructure of the material has anisotropic characteristics, the two-dimensional metallographic observation cannot reflect the directional difference, but also even under the condition of isotropy, if abnormal coarse grains exist in the microstructure, the maximum diameter of the grains is often misjudged, and because the observation surface is difficult to ensure that the grains are always positioned at the maximum interface of the coarse grains, the requirement of quantitative statistics is difficult to achieve.

Although the need for constructing three-dimensional metallographic structures is not strong in general cases, in some high-end materials, the results of three-dimensional reconstruction are more and more regarded by academic circles and engineers, and even in some high-impact factor journals, the results of three-dimensional reconstruction studies are common and are cited in large numbers in { Wu K m.script material, 2006,54(4):569 + 574}, { X.L Wan, r.wei, et al. Layer-by-layer information extraction is the main mode of three-dimensional reconstruction work at present, however, most of the three-dimensional reconstruction work results in reports are finished manually, so that the efficiency is relatively low, and the waste of precious working time of scientific research personnel is caused.
