Comparative analysis of the mechanisms and kinetics of mechanical alloying in the systems Fe(75)X(25) (X= Si, C)

Mossbauer spectroscopy, X-ray diffraction, and thermomagnetic measurements were used to study in detail the mechanical alloying of iron powders with carbon and silicon in the atomic proportion 75:25. Differences in the sequence and kinetics of solid-state reactions caused by differences in the atomic radii of the components were found. The microscopic mechanisms of deformation-induced atomic mixing are proposed.
