Determination of the Size-topological Parameters the Structure of Cast Iron

Abstract

The methods of geometric identification and determination of the main size-topological parameters of the graphite phase in cast iron are studied. The methods used in world practice to identify the form of graphite inclusions are considered. It is proposed to use the methods of fractal geometry for the determination and identification of graphite inclusions in cast iron. A method for determining the size-topological characteristics of the graphite phase in cast iron has been developed. To describe the non-uniformity of the distribution, the lacunarity function was used. An example of determining the size-topological parameters of the graphite phase for various types of cast iron is presented.
