Abstract
Introduction. Steel with pearlitic structure is characterized by good plastic properties in combination with strength, therefore, have a wide range of applications. Due to the low content of alloying elements, they are a promising material for use in various industries and from an economic point of view. To analyze the structure of plate-like perlite of various dispersity, it is proposed to apply a multifractal analysis, which is used to describe inhomogeneous objects. Materials and methods. The scoring scale from 1 to 10 for the plate perlite according to GOST 8233 was investigated by calculating the spectrum of statistical dimensions. Results of the experiment. The numerical values of the dimensions of the components of lamellar perlite and cementite D-100 and ferrite D100 decreased with increasing interplate distance from 0,2 μm (point 1) to 2 μm or more (point 10). Conclusions. Dimensional estimates of lamellar perlite of various dispersity can be used along with its scoring when predicting the quality of a metal based on an analysis of its structure.
