Hi,

1. You can use ImageJ or Image proPlus forSEM images.

2. You can also use SPIP

3. The Intercept method: A straight line drawn through the micrograph. Count the number of grain boundaries intersecting the line. Then,

Average grain size =1/(number of intersections/actual length of the line).

[where actual line length = measured length divided by magnification]
