Mechanical properties of board-bronzed wire depend from one side on the wire rod microstructure from which it is produced and from the other side – determines by peculiarities by the microstructure of the wire itself. At present, there are no generally accepted methods of deformed wire microstructure analysis allowing establishing relationship between characteristics of wire deformation and microstructure characteristics. A mathematical apparatus and new algorithm for processing of microstructure of pearlite steel wire after drawing elaborated based on microstructure image processing and its parameterization. As the main parameter of microstructure, the density function of statistical distribution of fiber lengths used, which allows characterizing quantitatively image of microstructure. Based on the experimental data of OJSC “BMZ – management company of “Byelorussian metallurgical company” holding” correlation demonstrated between degree of wire twisting and degree of delamination. On the basis of samples of perlite steel and their images obtained for bronzed bead wire manufactured at OJSC “BMZ – management company of “Byelorussian metallurgical company” holding” density functions of statistical distribution of perlite microstructure fiber length for the group of samples calculated. Criteria for wire microstructure analysis, based on density distribution function along length of fibers, as well as reduced distribution function proposed. Correlation between degree of delamination, number of wire twists and characteristics of its microstructure determined, calculated using the distribution function of wire fibrous structure with pronounced texture in the cross section.
