Аннотация
The structure of high-strength 09Kh16N4BL and 14Kh17N2L stainless steels produced by casting on fusible models is studied. The influence of the steel composition on the content of nonmetallic inclusions in the cast steel is of considerable interest. The morphology of the nonmetallic inclusions is studied, and they are identified. Fractographic analysis shows that the nonmetallic inclusions affect the failure of the stainless steels. Two methods are used for quantitative assessment of that influence. Besides the classical methods, multifractal parameterization of the structure is employed to study the structure of the stainless steels. On that basis, correlations are established between the main multifractal parameters and the mechanical properties of the steel.
