Notes:
At the early stage of mechanical alloying of α-Fe and ε-Co lamellar layers of the initial phases are formed. As the thickness of the layers decreases the interdiffusion of the elements starts and a disordered crystalline Fe-Co solid solution is formed. The progress of the solid state reaction has been monitored by Mössbauer spectroscopy, x-ray diffraction, and measurements of the saturation magnetization. The experimental data allow calculation of the change of fractions of material with different local compositions as the alloying proceeds. The main results are that Co diffuses into the α-Fe while Fe does not diffuse into the ε-Co. In spite of a much lower negative heat of mixing, the reaction proceeds in a similar way to the formation of amorphous NiZr during mechanical alloying.
