Automatic measurement of pearlitic interlamellar spacing with computer image processing.
ISIJ International, 1990 For metallurgical studies or routine control of eutectoid steels, it is necessary to perform automatic measurement of pearlitic interlamellar spacing. Various methods, using a combined system of a scanning electron microscope (SEM) and an image analyzer (IA) have been compared and the optimum procedure has been studied.
