摘要

Statistical and characterizing full-field method of fluid stress in the micro-range for microstructures of alloys, which comprises the following steps: a) The grinding and polishing of the surface of an alloy sample to a high-gloss finish without grinding errors and then the definition of an area to be measured on the surface of the alloy sample; the size of the area to be measured being 1 - 25 mm × 1 - 25 mm; b) the use of a white light interferometric 3D surface profilometer to measure the initial morphology on the surface of the alloy sample in order to determine the size, obtain the spacing and length-to-width ratio of microstructures on the starting surface of the alloy; c) using isostatic pressing technology to obtain the microstructural deformation on the surface of the alloy sample, and then using a white light 3D interferometric surface profilometer to measure the deformed morphology on the surface of the alloy sample to obtain the size, spacing and length to width ratio of the deformed microstructures on the surface of the alloy; to perform the statistical analysis based on the comparison between the size, the distances and the ratio of length to width of the microstructures on the surface of the alloy and those on the deformed microstructures on the surface of the alloy to obtain the deformation data on the surface of the alloy to obtain; and the mapping to obtain the deformation resistance of the microstructures on the surface of the alloy; and the associated calculations to obtain a spectrum of changes in micromorphology in terms of size, spacing and length to width ratio of the microstructures on the surface of the alloy based on the distribution of resistance to deformation of the microstructures on the surface of the alloy; d ) performing the oversized and rapid characterization of the quantitative statistical distribution of the morphological changes before and after isostatic pressing of the microstructures in the area of the alloy to be measured, so that a corresponding full-field metallographic spectrum is obtained.
