FRACTAL ANALYSIS OF MICROSTRUCTURES IN GRAPHITIZED CAST IRON

Abstract

The dimensionaltopological parameters of a structure such as size, shape, quantity and distribution characterizing a graphite phase in cast iron exert a significant influence upon material properties. But, the definition of these parameters according to the system presented in SARS 3443-87, to the considerable extent, depends upon human factor. The use of results of such an analysis does not allow creating adequate simulators for the estimation of correlation of structure and properties. The widespread introduction of computer analysis methods for the control of material structures dictates new requirements to the development of methods using a mathematical description of material phase structure. One of the methods based on a multifractal analysis of cast iron microstructure representation is shown in this paper. Data obtained at the use of carbon fleck fractal identification method can be used at the development of simulators of the correlation in structure graphitized cast iron properties.
