Grain size line intercept method
WebThe mean intercept length is probably the most accepted method for the estimation of grain size. 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.

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 ...
WebOne of the simplest techniques to estimate an average grain size is the intercept technique. A random straight line is drawn though the micrograph. The number of grain boundaries... WebThe intercept and planimetric methods are always applicable for determining average grain size. However, the comparison charts cannot be used for measurement of …
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 4, 2013 · The overall measured grain sizes for all four specimens were: 9.89 (planimetric method), 10.39 (three-circle intercept method), 9.92 (intercepts using three directed test lines) and 9.94 (intercepts using all six directed test lines).
