The initial stage of mechanical alloying (MA) in a binary mixture of powdered Al and 57 Fe in an atomic ratio of 99: 1 has been studied using X-ray diffraction and 57 Fe Mössbauer probe spectroscopy. The proposed microscopic model of MA includes the formation of a nanostructured state (∼15 nm) in FC...
