Application of optical-mathematical analysis methods of dispersion of high carbon alloys structure

Abstract

In the present paper we carry out the heterogeneity estimation for high chromium cast iron via methods of optical-mathematical analysis. This includes the assessment of dispersion structure using the parameters that describe the function of energy and stress dissipation resulting from the structure formation processes of such alloys. We show that heat treatment significantly affects the change in the sign of stress functions of strain and power dissipation for the high chromium cast iron. The number of parameters with positive and negative sign increases dramatically because of reducing the neutral (zero). This corresponds to the above analysis of the chains length of pixels of the same color. As it follows from the current research, change of sign in the function of dissipation power is a matter of scientific and practical interest from the point of view of the behavior of various materials during their production and use. The preliminary studies have shown that most of these structures have positive or neutral sign of power dissipation function, while a negative sign is observed in isolated structures. It is shown that for vertical dispersity values of fineness of the vertical heat treatment after increasing the number of local areas with pixels in which the values are increased and co-Laplacians amount of conventional colors correspond ferrite structures with increased carbon content. Obviously, such local area can be attributed to regions of increased dislocation density.
