Effect of silicon on the phase formation in mechanically activated systems based on [Fe.sub.75][C.sub.25]: mechanosynthesis of composite states

The methods of X-ray diffraction analysis, Mossbauer 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...

Description
Summary:The methods of X-ray diffraction analysis, Mossbauer 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 [less than or equal to] 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.
