Anisotropy of the Structural Inhomogeneities of Rapidly Quenched Alloys

Resumo

Fe₇₀Cr₁₅В₁₅ alloys produced by rapid quenching from the liquid state in the form of ribbons (melt spinning technique) at various condenser spinning rates (v = 5, 10, 20, 30, and 45 m/s) are investigated. The Lebesgue formalism is used to describe the spectra of spatial heterogeneities on microscopic images of the microrelief. In terms of the linearized Kullback divergence on the Lebesgue integral measure functions, melt spinning technology parameterization is suggested. The possibility of structural-ordering diagnostics at the micro-level according to the microrelief statistics is demonstrated. The model of the melt spinning process is constructed on the basis of statistical representation of the microrelief.
