Evaluation of Numerical Characteristics of True Interlamellar Spacing of Pearlite in Eutectoid Steel After Cold Wire Drawing

Popis výsledku v původním jazyce

Alloys that have lamellar structures, e.g., pearlitic steel, are widely used in practice. Nowadays, perlitic steel wires for tyre cords, springs and ropes are studied extensively at our laboratory of wire drawing. In the metallographic analysis of pearlite, the interlamellar spacings observed are not true spacings because the lamellae usually are not oriented perpendicular to the observation planes. The measured interlamellar spacing is called apparent. Evaluation of true interlamellar spacing from microstructural observations is based on the assumption of a uniform distribution of the probability of the angle between lamellae and the observation plane. As the lamellae change their orientation during cold wire drawing, this assumption no longer applies. This paper deals with evaluation of numerical characteristics of true interlamellar spacing in drawn pearlitic steel wire. We analyzed wires from C78D steel for ropes upon varying degrees of deformation.
