Engineering Physics Annotation << Back MOSSBAUER SPECTROSCOPY STUDY OF STRUCTURAL AND PHASE TRANSFORMATIONS IN Cu-Fe DURING MECHANICAL ACTIVATION М.А. EREMINA, A.L. UL’YANOV, S.F. LOMAYEVA Mössbauer spectroscopy and X-ray diffraction have been used to study the kinetics of structural and phase transformations in Cu + 2 at % 57Fe during mechanical activation in distilled water. The initial stages of mechanical alloying are associated with the transition of components to the nanostructural state. Oxidation of groups of iron atoms that form highly dispersed phases of ternary oxide and magnetite occur in the initial stages of mechanical alloying. The isolated iron atoms penetrate from the boundaries into the grains and the formation of the solid solution containing up to 1 at % of iron proceeds. Key words: nanostructured materials, phase transformation, mechanical alloying, Mössbauer effect, Cu-Fe.
