WebApr 2, 2012 · This program allows you to analyze the size of grains in a micrograph with the intersection method arranged in a user-friendly GUI. After loading the micrograph the program puts lines on the surface. Now you have to use the cursor to click on the intercept of the lines with the grain boundaries.
WebFeb 21, 2024 · It is not sufficiently accurate for quantitative grain size measurements. The intercept methods involve the random application of a test line of known length (L T) on the microstructural image and the counting of the number (n) of either grains that intercept the test line or grain boundary intersections that lie on the test line.

In the intercept length method, the polycrystalline microstructure is generally superimposed by a grid of parallel lines (see figure 2.2b) and the number of intercepts (intersections with grain boundaries) per unit length ( P L ) is obtained.
WebJan 1, 2024 · The mean linear intercept -method (MLI) is traditionally used to acquire average PAG sizes from light optical microscopy images, which are from experimental test samples. The MLI -method is arduous and time-consuming as well as a highly generalizing method, where you lose information about the grain size distribution. Therefore, a more ...
