Abstract��Taking the typical pearlitic steel U75V as an example, a method of measuring the average pearlitic interlamellar spacing in steel by electron probe microanalysis (EPMA) was introduced. Choosing the scanning path as perpendicular to pearlite interlamellar as possible, the curve of C content alternated as ��wave trough�� and ��wave crest��. The distance between two "wave trough" or two "ware crest" is one pearlitic interlamellar spacing. The method is direct, simple, and the measurement of pearlite interlamellar spacing is close to the true value.
