Abstract

Many alloys that have lamellar structures, e.g., pearlitic steel, are widely used in practice. For the evaluation of the quality of steel wires for tyre cords, springs and ropes are studied extensively at our laboratory of wire drawing. An important prerequisite for right evaluation is the accuracy and consistency of the evaluation of true interlamellar spacing from microstructural observations. In this paper we used the basic techniques for evaluating whether there are significant differences in the measurement of interlamellar spacing among different researchers. For this purpose were produced samples of steel wire by the straight-through single-block KOCH KGT 25 – E wire drawing machine. The analysis was performed on the 1.5 and 3.4 mm wires from C78D steel for ropes with various degrees of deformation.
