Abstract

The mesorelief of the surface of plastically deformed specimens is characterized by a correlation function. It makes it possible to determine the fractal dimension Dc and the correlation length ΔL from surface images of the studied specimens obtained under light and scanning electron microscopes. It is shown that two modes of behavior of the correlation function can be distinguished for specimens of iron suicide and austenitic steel broken in the process of active stretching. In one mode Dc and ΔL characterize the mesorelief of the surface at scale levels less than the grain size (Dc1, ΔL1) and in the other they describe it at scale levels on the order of several grains (Dc2, ΔL2). The behavior of Dc1, ΔL1, Dc2, and ΔL2 is studied as a function of the distance from the head to the breakage place for specimens of iron silicide and as a function of the degree of plastic deformation for specimens of corrosion-resistant steel. The characteristics increase stage-by-stage with increase in the degree of plastic deformation until the specimen fails.
