Growing use of high-strength low-alloy steels in additive metal structure manufacture is accompanied by an increase in the requirements to the reliability of prediction results in the “composition-structure-properties” system. Application of fractal analysis methods allows establishing the metal structure characteristics by numerical parametrization, the metallographic analysis of which gives only a qualitative assessment. The paper shows the possibilities of fractal analysis for numerical evaluation of such characteristics of additive metal structure as the total length of grain boundaries, distribution of dislocations at the grain structural boundaries, distribution density of nonmetallic inclusion accumulations at a distance less than 5r from one another. Shown is the possibility of numerical parametrization of the structure and nonmetallic inclusions in the “structure-fractal-properties” system for predicting the mechanical properties of additive metal of high-strength low-alloy steel type. 7 Ref., 7 Tabl., 9 Fig. [ABSTRACT FROM AUTHOR]
