Steels — Manual point counting method for statistically estimating the volume fraction of a constituent with a point grid 钢与粉煤灰;用点网格统计估算成分体积分数的手动点计数法
发布日期: 1988-12-29
适用于清晰可识别的成分(一个相以及由两个或更多相组成的显微组分)。点栅格叠加在观测表面的给定数量的场上。通过计算点数,计算体积分数。
Applies to constituents (a phase as well as a micrographic constituent composed of two or more phases) which are clearly identifiable. The point grid is superimposed a given number of fields of the observed surface. By counting the number of points the volume fraction is calculated.
