Effect of silicon on the phase formation in mechanically activated systems based on Fe75C25: Mechanosynthesis of composite states

Abstract

The methods of X-ray diffraction analysis, Mogsbauer spectroscopy, and measurement of dynamic magnetic susceptibility have been used to study stationary phase states that develop at the later stages of mechanical alloying in a planetary ball mill. In the Fe(100 − x)C(x), Fe(75)C(25 − x)Si(x), and Fe(75 − x)C(25)Si(x) (x ≤ 25) systems, the processes of phase formation are determined by the dynamic equilibrium between the crystalline and amorphous phases. Depending on the composition of the alloys, the conditions of this equilibrium are changed, which is reflected in the sets of the crystalline phases that are formed.
