系列截面分析方法是显微组织3D定量表征及3D重建的重要方法,为兼顾结果的准确性和效率,系列截面法中层间距的选取非常重要。本文选取不同仿真尺度(300×300×300和400×400×400)的Potts模型Monte Carlo仿真晶粒组织为研究对象,研究了系列截面层间距对三维个体晶粒的体积和表面积测量结果的影响规律,结果表明:系列截面的间距值h<0.111珋l和h<0.135珋l(珋l为晶粒平均截线长度)时,分别可保证晶粒的体积和表面积测量的相对误差小于5%和10%。
A series of cross-section analysis methods are important methods for 3D quantitative characterization and 3D reconstruction of microstructures. In order to balance the accuracy and efficiency of the results, it is very important to choose the interlayer spacing in the series of cross-section methods. In this paper, Potato Monte Carlo simulation of grain structure with different simulation scales (300 × 300 × 300 and 400 × 400 × 400) was selected as the research object, and the effect of the interplanar spacing on the measurement of volume and surface area of three-dimensional individual grains The results show that the relative error between the measured volume and the surface area of the grains can be guaranteed to be less than 5% when the spacing values of the series of sections are h <0.111 珋 l and h <0.135 珋 l (珋 l is the average grain-cutting length) And 10%.
