【摘要】 利用系列截面法系统地研究了一种微合金化低碳钢奥氏体晶粒的空间及截面拓扑分布特性．实验建立了晶粒界面数Ｆ与其截面多边形边数均值及边数平方均值之间的经验关系，并进一步研究了不同拓扑级别的三维晶粒的截面拓扑分布且与多种晶粒几何模型进行了比较分析．更多还原

【Abstract】 A study was undertaken to reveal the plane section and spatial topology distributions of austenitic grains in a low-carbon steel using the serial section analysis. The relationships between plane section and spatial topology distribution characteristics of grains were determined experimentally. Observations and comparisons were made of the distributions of number of sides of sections of grains with different number of faces as well as those of three geometric grain models.更多还原
