“…Probably, one of the mechanisms of white layer formation in drawing is the interaction of profile peaks and irregularities with the die. [47] With further processing the gradual smoothing of profile irregularities on the wire surface occurs and its effect on the layer formation diminishes. For deeper understanding of the mechanism of white layer formation it is necessary to conduct investigations using precise methods of metallographic analyses.…”

White layer which is formed on the contact surface between a wire and a die depends on deformation conditions. The aim herein is to obtain the model for the assessment of white layer thickness which is formed in the combined deformational processing by drawing with torsion in high‐carbon 0.7%C steel wire. Finite‐element modelling is used to predict the thickness of the white layer. A series of experiments in the combined deformational processing of high‐carbon steel wire is conducted at different deformational conditions. Using the quantitative coefficient of anisotropy that characterizes the shape of grains, the thickness of white layer is measured. It is found that the theoretical prediction of white layer thickness matches with experimental data. In addition, the mechanical properties of the processed carbon steel wire are studied by the tensile test.

“…Review of such methods is presented in [1,2]. It is proved both theoretically and experimentally that at drawing on the contact boundary «wiredrawing die» the thin layer with 20-40 μm is formed in which deformation intensity of the metal is higher than deformation of bulk material [3,4]. This is of high importance for drawing the wire of small diameters.…”

Drawing is characterized by non-uniform character of plastic deformation, which is transferred from the die to the processed wire. Such impact causes specific change of wire microstructure. In the surface area the thin layer with highly deformed grains is observed. It is important to measure the thickness of this thin layer. For this purpose it is proposed in this paper to use the value of coefficient of anisotropy, which is calculated as the ratio of mean quantity of phase particles, crossed by secant line perpendicular to deformation axis on the unit of secant line length to the mean quantity of phase particles, crossed by secant line parallel to deformation axis on the unit of secant line length. Distribution of coefficient of anisotropy, both for low and high carbon steel wire after drawing, was obtained by Thixomet PRO software. It made it possible to calculate the thickness of highly deformed area automatically taking into consideration the difference of steels microstructure.
