A correlation function is suggested for characteristic of surface mesorelief of the plastic-deformed specimens of Fe+3.2%Si and Kh18N10T steel. It enables to determine a fractal dimension (Dc) and correlation length (ΔL) from surface images obtained in the electron microscopes. An availability of two correlation functions is ascertained for silicon iron and steel specimens, fractured under active tension. The primary and second functions characterize the surface mesorelief at the scale levels lesser and more than grain dimension respectively.
