FIELD: investigating or analyzing of materials.
SUBSTANCE: method comprises choosing a region on the visible image of grain structure of metal, applying two mutually perpendicular sets of secants, and measuring the lengths of the chords formed by intersecting of the boundaries of the grains by the secants. The grain size is determined from the measurements performed.
EFFECT: expanded functional capabilities.
