摘要：
Structure-phase transformations in the 68Fe-32Sn system by mechanical alloying from pure elements and mechanical grinding of a multi-phase alloy for different conditions of mechanical treatment in planetary ball mills were studied by X-ray diffraction, Fe-57 Mossbauer spectroscopy and magnetic measurements. The initial stages of structure-phase transformations by mechanical alloying and grinding were found to be different. However, the final product in all cases was nanocrystalline supersaturated solid solution of Sn in alpha-Fe with the bcc lattice parameter a= 0.2995 nm, the magnetic moment per Fe atom mu(Fe)=1.9 mu(B) and the Curie temperature T-c=700 K.
