STATEMENT ON THE ISSUE OF THE PROBLEM IDENTIFICATION OF FRACTAL METAL STRUCTURES

To study the structure of metals and alloys and its influence on their properties are widely used traditional methods of macro- and microanalysis, X-ray, spectral, thermal and inspection (X-ray, magnetic, ultrasonic). They have their own threshold, often narrowly focused and applied directly depending on the purpose of the research object (pipe, forming rolls, metal, etc.). Currently existing mathematical models of forecasting the qualitative characteristics of metal products based only on an analysis of statistical data do not provide physical-chemical interpretation of the processes that occur during the formation of the structure or who could definitely take into account the effect of the chemical composition and other parameters of the technology. Therefore, the forecast results can not always meet the requirements. In order to obtain acceptable quality results produced by the product specifications developed by the forecast methodology should include the use of both classical and modern methods of structure evaluation. So, to determine the relationship between mechanical properties and structure elements of cast iron roll is planned to use the theory of fractals and multifractal. The proposed method is the most appropriate to quantify the majority of real structures, which the integer approximation of the figures of Euclid introduces some uncertainty, and therefore not always acceptable in practical problems of modern materials. In this regard, it is assumed conducting special experiments, the analysis of which allows to develop a qualitative evaluation of the mechanical properties of the investigated steels and cast iron. As a result of analysis of the production technology of steel and iron and research work aimed at solving the problem of evaluating the mechanical properties of the formulated problem statement of operational forecasting of these properties and the basic ways of its solution.
