Astm E562-19e1 [repack] -

To quantify the amount of a specific phase (volume fraction) in a material. Systematic manual point counting using a grid overlay. Importance

At the heart of E562 lies the principle of stereology —specifically the fundamental relationship established by Delesse in 1847: the volume fraction of a phase in a three-dimensional material is equal to the area fraction of that phase on a random two-dimensional cross-section ( ( V_V = A_A ) ). E562 extends this concept by noting that the area fraction can be accurately estimated by a point fraction ( ( A_A = P_P ) ), where an array of grid points is superimposed on the microstructure, and the fraction lying on the phase of interest is counted. astm e562-19e1
